Webinar this weekend.

Written by Nathan Foster on December 18th, 2021.      0 comments

Hi everyone, I hope this email finds you well during these challenging times. It has been a long time since my last post however I am happy to report that we are still at the coal face. This year has nevertheless presented us with some difficulties with regards to how we deliver our business. Following issues with the Paypal system, we had to retire this service which in turn has affected how we deliver some of our services. It is also worth noting that we are seeing some problems with some email services due to the subject matter (i.e. ballistics / rifles etc.). Emails sent from myself or the website, including order confirmations and download links, may go to the recipient’s spam folder as a result of increased internet security measures. Emails and download links can nevertheless easily be retrieved from the customers spam folder. It is simply a matter of being aware of mail handling. If you have ordered a product and do not for example immediately receive a download link, you will find the email within your spam folder.

Free webinar this Sunday (Saturday Northern hemisphere)

Time: 8am Sunday 19th December, Auckland NZ time. (Eastern Standard Time: 2pm Saturday 18th December)

Web link:

One thing I have been trying to work through is a way that we can all communicate in a more meaningful manner. As much as I have enjoyed the youtube podcasts, they were always one sided with the viewer only able to communicate within a text box which made it very hard for the viewer to provide context to questions. We looked into zoom conferencing but this is quite expensive and I was hoping to be able to offer seminars either free of charge or at a low cost to our viewers.

I believe we have found a temporary solution via This is free open-source software and users do not need to create an account to use this platform. We are going to trial Jitsi this weekend (see time above). Once at the url (given above), all you need to do is enter your first name or a nickname and press the join meeting button. You will of course have to make sure that your camera and microphone are turned on. The downside of this platform is that it has a limit of 100 people per session, therefore we will have to do this on a first come, first serve basis.

There will be no specific topic for this weekend’s webinar. If you can think of any questions you would like to ask me between now and the weekend, write them down. I am hoping that via video conferencing I can provide greater clarification to specific questions rather than get lost in generalizations. Although this is a free webinar, if you find the information useful and are in a position to help, a small donation thereafter would be appreciated.

Just keep in mind that there may be a few mistakes as I trial this. I am not the most tech savvy.

Video Learning

One positive aspect of the challenges mentioned at the beginning of this email is that we have been forced to look at better delivery systems for our products. Customers will be happy to know that our learning series videos are now hosted on our website as direct downloads. As these are downloadable products, we ask that you please do not share them. The funds from these video help to support our family along with ongoing research. Link to video series:

The video files are formatted to MP4 H264 and are generally very large (e.g. 3 to 5 GB), you may therefore wish to use a download manager. This software tool helps to ensure that your video will continue to download if you have a poor (or dropped) connection. A free open-source download manager can be found here:

Following a purchase, you will immediately receive two automated emails. The first is your order confirmation. The second email contains a link to your download. If you cannot see the download email, then it is most likely in your spam folder. If you do not receiver either email, then you have most likely entered an incorrect email address when placing your order.

Note that you only have two days to download the file from the email link. The link will expire thereafter (for our security). If you fail to download your file as a result of either an incorrect email address or expiry, we will do our best to help (or provide a refund) however you must take some responsibility for your purchase by entering the correct details and downloading the file immediately.

Note also that some of the latest Apple computer video players are set by default to H265 video format. You will therefore need to make sure that the video player on your Apple device is set up to play H.264 codec videos.

To check that your player will play these videos, click here to download a test video.

Apple / Mac users may also want to try the free VLC media player:

Well, that’s about it from us. I would like to take this opportunity to say thanks to each of you for supporting our business and family along with your very kind and supportive emails which brighten our days. I cannot thank you enough for such kind gestures. I do hope that you have been able to get away hunting this year, or at the very least taken time to relax in the wilderness or perhaps engage in practice shooting.

From our family to yours, we wish you all the best for this coming Christmas and the following new year.


New videos

Hi all, I hope this blog post finds you well. I just wanted to share a couple of videos. 

The first video contains a few highlights from a talk I gave to the Manawatu regional branch of the New Zealand Deer Stalkers Association. Subjects covered: Fast killing, the rise in popularity of low powered cartridges, Berger bullets.

The second video features a book reading and Interview with regards to our most recent publication - The Door. The host, Andrew Carter, is a New Zealand producer who specializes in the filming of MMA and Kick boxing events within NZ and abroad.


Effective Game Killing - Part 2

Written by on February 18th, 2021.      0 comments

Hi all, just a quick catch up. Steph and I have been busy as usual, engaged in ongoing research and writing writing projects. Following the chaos last year, we decided that we really wanted to continue to knuckle down and stay focused without distraction. So while it may seem that we have been rather quiet, we have been at the coal face through Jan / Feb. Will disclose project details at a later date.

Norma have uploaded part two of my Effective Game killing article. Links to 1 & 2 below:

November 2020 - Nathan Foster

Written by Nathan Foster on November 21st, 2020.      0 comments

Hi everyone, here we are are near the end of another year.

Christmas orders

First, a reminder that Christmas is not far away so those wishing to order paperback books may want to do so within the next week or so before the printers and post services get swamped (New Zealand buyers please note that we have stock here in NZ for domestic shipping). If you purchase ebooks there is no waiting, just follow the link you receive with your order confirmation, download your books and enjoy.


.44 calibers added to the knowledge base (KB)

I have finally had the time to sort through my .44 cal research. Yep, took me long enough but it is finally done. Articles include .44-40, 44 magnum and .444 Marlin.  It’s great to have these finished and up for your enjoyment, I hope each of you find these articles useful.


Norma work

As most of you know by now, I have been working with Norma this year, writing educational material. The first project was an updated and highly in-depth version of my Effective Game Killing article. Norma has taken an incredibly brave approach with this article, allowing me to explain not only the strengths of their ammunition, but also limitations. This level of transparency is rare these days and shows the commitment that Norma have made to their customers. I am deeply honored to have this opportunity to be a part of this meaningful project. A second article will appear in the near future (shot placement). From next year, I believe I will be working as a consultant to Norma in one capacity or another.


The Door

If you want to know a little more about me, the Door is the book to read. The inexpensive ebook option also serves as a great way to donate to the site while getting more bang for your buck.

A review from the forums:

I just had a chance to pick this up and read it and wanted to add my recommendation to anyone on the fence about picking this book up! I didn't grab the book right when it came out, not because I didn't think Nathan and Steph's backstory wouldn't be interesting but because I personally can't stand nightclubs, clubbing, clubbers or anything to do with that scene so I thought I would put it on the backburner. Reading some of these positive reviews made me pick it up and I am sure glad I did. While I figured reading about your backstory would be interesting (and it was), I enjoyed the book a lot more than I expected. Even though I can't stand nightclubs at all, what I really found compelling was a couple of unexpected things; Nathan's growth from a young 'karate kid' into a true warrior, and also the very interesting insights into human character, especially the nature of violence.

In hindsight it makes sense to me that in our oh so cleaned up modern western societies, with no room for men to be warriors that being a doorman at a nightclub is one of the few places left for a man (or woman) to have that no BS laboratory for developing hand to hand combat skills, and into a warrior. For anyone even vaguely interested in hand to hand combat, martial arts or the warrior mindset I would say this book is a must read, ten bucks is hardly anything to pay for Nathan's insight into those topics.

Anyway, I am certainly glad I took the time to read this book and I encourage anybody on the fence thinking about it to go ahead and read it, I don't think you will be disappointed.

Great job Nathan and Steph, and God bless you and your family!



Over the last couple of years, I have had to back off my email in order to avoid being ground into a state of non-productivity. But as and when time has allowed, I have copied the occasional technical email exchange to a book draft titled Ask the expert. So far the book is up to about 200 pages of useful tips and tricks. I will keep plugging away at this but as suggested, this book is being written only when time allows.

Another method I have been employing to deal with mail is Vimeo record. A supposedly simple platform for answering mail by video.  One aspect that I like about this is that it allows me to really give you guys my undivided attention, it allows me to really connect with you in a way that email cannot convey. On the other hand, there are some limitations. Vimeo record was designed to help work flow but the method is only convenient if I use my laptop (low quality picture and sound). In order to record at a higher quality, I would need to set up a studio which kind of defeats the purpose. It’s also not so easy to have a one-way speaking conversation. I end up feeling that I am trying to fill my own gaps in thought with speech when I should be sitting quietly and thinking about possible contradictions that may be helpful to the person who has emailed me. Perhaps over time I will get better at this.  In any case, after recording my waffle, the video is saved to Vimeo where it can be shared privately to the person who emailed me via a quick link.  Videos suitable for sharing can also be saved to a channel which everyone can view on Vimeo. The channel can be set to free viewing or paid subscription as a means to get something back from the time and energy expenditure. At the moment, I have just a few videos uploaded which are set to free viewing. Will see how this goes over time and whether it actually serves as an effective delivery method.


End note

Well that’s about it for this year guys. It’s been a tough one for sure. If I can offer one piece of advice moving ahead, it is that the measure of one’s strength and power is perhaps equal to one’s capacity for gratitude and compassion.  It is this I believe that separates us from those who prefer to shed personal responsibility and want to change others in order to make themselves happy.  To that end, I wish each of you great strength and power. 

Merry Christmas everyone.

Nathan, Steph and Miss Riley.


Norma Article - Nathan Foster

Written by Nathan Foster on November 7th, 2020.      0 comments

Hi guys, sorry I have been a bit absent just lately but its all been for a good cause. Here is what I have been up to:

1. Some time ago I was contacted by the management of Norma Sweden. After kindly stating that they were big fans of my research, I was asked if I would like to write education educational material on behalf of Norma. Somewhat jaded by the current (BS) state of the industry in general, I sent a curt reply, clearly stating my thoughts about the new generation of manufacturers, fully expecting that I had just burned yet another bridge. To my surprise, Norma came back to me with open arms - We totally agree, so what do you want to write about? Well I replied, any educational material needs to be built on a solid platform. The fundamentals have to come first. What I would like to do, is update and rewrite my treatise on effective game killing, using Norma ammunition in my examples. But further to this, I am sick and tired of "miracle" bullets so I would like to show not only the strengths of your ammo, but also the limitations. Its high time we had dome transparency in this game and if you care about your customers, then you will allow me to take this angle. Send...

Again I received another kind and agreeable email. Norma management were just as tired of the modern marketing machine as myself. It was time to cut to the chase, to relight the fire, the passion, that 1960's sense of invention and wonder. And so with Norma's blessing, I wrote an updated and highly in depth version of Effective Game Killing. I hope this conveys my sincere respect toward Norma for their bravery in taking this route and serves as a truly useful educational tool. I hope also that it stands as a source of pride for Scandinavian hunters.

I will continue working for Norma in one capacity or another, whether writing or consulting. It is a great honor and I am taking this position most seriously. I know a lot of you are counting on me to keep the flame burning in this game.

2. I finally took some time to sit down and go over all of my .44 cal data! It is pretty much ready for uploading but I will need to compile the tables for the bottom of the article. When I say ready for uploading, my version of editing is to sit down, pull my notes apart, cross examine myself, retest various elements, put it all back together again and then wonder why there are now more squiggly red lines under the words of my edited document than when I first assembled the data several years ago. So it may just be that the article goes live with a few typos. The .44's will nevertheless contain a pile of information which I am sure you will all enjoy. If I am quick enough, it might also give our U.S readers a small distraction while they wait to see the outcome of their current election.

Well, thats about it for me. I will write another post / blog post once the .44's are live. All the best guys.

Hi All, just a quick post to say that we will be running another youtube live stream in NZ this Sunday at 8am (Saturday afternoon or evening for Northern hemisphere viewers).

Please click on the following link to view the correct screening time and countdown clock for your region:

This week’s chat will be organic as usual. I will most likely start the stream with the first email or live chat question that peaks my interest or that which may be of use to others.

Until then, all the best.



The Door - New Book By Nathan Foster

Written by Nathan Foster on July 28th, 2020.      0 comments

Hi All, today is a very special day for Steph and myself as we announce the release of a new book!

This has been a long time coming and I guess it will come as a surprise to many of you as I have not spoken about this book previously. Many of you have over the years, wanted to know more about myself at a personal level.  The Door is my story, a biography of my journey. Please be aware that this is not a hunting book.

The Door is a co-authored effort between Steph and myself. I wrote the initial draft to lay out the foundations but the story was often so dark that I could not fully relate this journey on my own. Thankfully, Steph also has an immense talent for writing. Although Steph had lived through many of these experiences with me, having read the draft, she sat down and interviewed me while taking notes, sometimes having to drag the memories from me. In this manner through Stephs co-authorship, we were able to put these experiences into print.

A Graphic Guide For Military, Police & Medical Personnel

A new book by Nathan Foster.

Please note - This is a semi-restricted item. To purchase this book, buyers must supply a covering letter (email) stating their intention. This book is designed for government organizations but may also be purchased by individual soldiers, officers, medical staff or ex-service members. However as stated, buyers must apply by email before making a purchase.  Once we have replied to you and confirmed your request, you can come back to this page and make your purchase.

No email - no purchase!

To view or apply to purchase this book, please click here.

Small Arms Wound Ballistics is a large (8.5 x 11 US Letter) hardback, case wrapped full color print book, 191 pages.
This book details the wounding effects with common eastern and western military cartridges, police issue cartridges and those commonly used to commit crimes. SAWB covers such subjects as wounds produced by the .22 Long rifle, effects of the 12 gauge loaded with buck or slugs, handgun wounding, all the way up to the effects of the .50 BMG. This book shows in graphic detail real world comparisons between such cartridges as the 9mm compared to the .45 ACP including barrier test results.

SAWB was written as reference material for both the trainee and academic. It is a no BS book for cops, infantry soldiers, snipers, security contractors and medics. It casts away myths and gets to the point. And yes, its quite graphic, starting off with some fairly dramatic head shots and getting heavier from there. Above all, it's about getting to know your tools and learning what you are up against.

December 2018 newsletter

Written by Nathan Foster on December 10th, 2018.      0 comments

Hi all, I hope this news letter finds you well. 

This is just a brief news letter to let everyone know (especially wives) that we are near our deadline for Christmas book deliveries (postal services slowing down under heavy workloads). If you are wanting to buy a book set for a friend or partner for Christmas, please consider making this purchase within the next few days.

Note also that if you are concerned about delivery at this time, you might (again speaking to wives) like to consider the paperback + ebook version of the books. This will ensure that you have an immediate copy of the ebook files (zip folder – pdf, epub, mobi) which can be hidden away on a hard drive until Christmas day.

Please click here to shop for books (link to entire collection 25% discount).

What else has been happening? Well its been a challenging year for us. I was laid up ill for several months and am just now starting to rebuild some strength. This slowed down progress a great deal but we can now finally look at getting back on track with our projects for the coming year.

As some of you know, I have for the last year or so been working with Dave Manson towards optimizing some of our traditional cartridge / reamer designs. The goal has been to enhance potential with modern projectiles for which these cartridges were never designed. We are now getting closer to finalizing these designs which include the .280, .280 AI, 7mm Rem Mag, .30-06, .30-06 AI and .300 Win Mag. I won’t say too much more at this stage but would simply like to raise an awareness of the new reamers for those planning builds for 2019. The reamers are for your benefit, to make life easier on barrel makers, the smiths who fit the barrels and the guys who then have to shoot the rifles. Ease of accuracy, power, magazine lengths and throat longevity have each been taken into consideration. Please do not email me with questions about these at this stage. When we are ready, I will release a highly deta iled newsletter with exact specs, OAL’s and so forth.

Dave Ann WL

Dave and Ann at SHOT, early in the morning before the crowds arrive. 

Note that we will be at SHOT in Las Vegas this coming January. David and Ann Manson have once again kindly offered to sponsor us at this event. The Manson booth is on the bottom floor and very easy to find. Simply walk in the main doors, set your gaze at about 2 O’clock and walk about 30 yards, you’ll see us there.


Would you like to hear me waffle on for an hour or so? The following is a podcast with Dave Byrnes, owner of the website Hunting Arete (Australia), dedicated to creating a positive and supportive network for hunters.

While assembling footage for our upcoming tutorial videos, we took a small section of footage and uploaded this to youtube, titled – Is it me, or is it my rifle? This is just a short video but highlights the importance of working through the basic variables. The rifle in question was a factory Remington M700 Long range Hunter chambered in 7mm Remington Magnum. The client had used the Accurizing book (see also Remington M700 troubleshooting video)to break the rifle in. Many of you will be interested to know that with regards to the bore, it required three throat lapping sessions to reduce fouling to a point where the rifle began to play ball. Following this, the client came to me for a tutorial with the goal of refining accuracy further. The youtube video is a small segment of this foo tage. Of the variables shown, please pay close attention to the issue of chamber tolerances versus brass tolerances, especially if you are using a suppressor which can cause carbon caking at the chamber. I would also like to remind each of you that concentricity needs to be considered a priority when working up accurate loads. If the bullet is not squarely aligned to the bore, accuracy will be poor. Those of you who wish to reach out long would do well to consider the likes of the Sinclair concentricity gauge as being at the top of your shopping list, above both dies and a press.

This video shows the 180 grain Hornady ELD-M in action. I have refrained from uploading this to a public channel as the footage is quite graphic. Therefore, please use the link above to navigate your way to this footage. It can also be found within my online article- The 7mm Practical.

Some old footage I recovered from a defunct camcorder. The quality and sound are terrible but those of you wanting to see a .375 RUM in action will enjoy it. In this video, I was testing the 300 grain Woodleigh PP. It was pushed far beyond its limits and if you look closely, you can see that there was a risk of over expansion (shallow penetration). Still, this load and others had to be tested. Once again, this is an unlisted video so you will need to use the link here to navigate to this video. 

That’s about it for us. I hope each of you have a relaxing and enjoyable Christmas. Steph and I would like to extend a personal thanks to each of you for supporting us throughout 2018. We hope that you continue to find value in our research. 

Until next year, All the best.
