Lightening a heavy Barrel 33 months ago by Ben Grady Lightening a heavy Barrel

Hi guys My 25-06 weighs to much. I would have to check but around 5 kgs. Question is can I trim the barrel contour down without wrecking it. The barrel is 632mm long to the bolt face. 30.2mm thick at the chamber for 115mm long before tapering down to 16.92mm at the muzzel next to the suppressor thread. Being a quarter bore there is a lot metal. This makes it pretty heavy. Its accurate and good to shoot prone but I have had a torn tendon fixed in my left elbow and I can't hold it off hand for any..

Re: versatile whisper cartridges ideas and thoughts? 33 months ago by Bryan Webster Re: versatile whisper cartridges ideas and thoughts?

Thank you for the data Bob. I am surprised you are using the Lapua Palma brass. I have been thinking of buying some for my .308. Have you noted better accuracy/consistency from them, and also have you annealed the cases yet, or just do not require to do so? Sorry Sebastion about hijacking this thread!

Re: versatile whisper cartridges ideas and thoughts? 33 months ago by Bryan Webster Re: versatile whisper cartridges ideas and thoughts?

Not so bad or overdone either as the load I was using was giving me 2100fps with a 400 grain bullet in a 7.5 pound rifle. One of our friends uses a lever action 375 Winchester and gets around 2100 fps from its 20 inch barrel using a 220 grain flat-nosed bullet. He hunts whitetail deer at close ranges and takes a black bear a year plus some coastal blacktail with it with no issues. The shape of the stock on the Win lever actions leaves something to be desired if a person has an aversion to recoil..

Re: P-14 found in the bottom drawer 33 months ago by Paul Leverman Re: P-14 found in the bottom drawer

Well, Thomas and Grant, it's looking really nice. The fit on your stock is way nicer than mine was. I just finished inletting the stock to suit the action. Pretty well all day. It seemed that every time one adjustment was made it bound up or pressed somewhere else. Back and forth. One of the hardest to find and fit was the area on the rear left where the radius of the action meets the stock. It's a good thing that most of what I ended up gouging out is well hidden. It looks like a rabid beaver h..

Re: .17 Hornet 33 months ago by Nathan Foster Re: .17 Hornet

Some good feedback here. I should have mentioned, annealing will make little difference. These very small bullets will heat up regardless due to bore friction and air resistance, right to their core. When they hit, they are very warm and malleable. Like I said, I have seen guys do this and in NZ, we all know of the swags of animals bagged with the .22LR, I have taken a good many animals myself this way. But situations like the one Bryan mentioned are very real, I have been in exactly the same po..

Hydrostatic shock 33 months ago by David Gray Hydrostatic shock

So, I was on another blog, board, website..whatever. One of those that is mostly about the M4 carbine. And clones....but that's another story. One of the members asked about if there were such thing as Hydrostatic shock. I sent him a link here. But apparently the boys at the M4 site have made up their mind that there is no such thing as "hydrostatic shock". It's a myth. Fudd science. Witchcraft. Etc. It stirred up a fairly big crapstorm and the thread was shut down. Ask, answered and debunked nu..

Re: New Theory to pick apart 33 months ago by Mike Davis Re: New Theory to pick apart

at 50 yards or less in the bush the tape wont matter stuff all,I believe its not recomended for .22 calibre centrefires as high degree of accuracy needed, on a recent thread on another site the question was asked about taping suppressors and one of the leading makers said yes do it. I do it but if remember remove it before shooting. never had any issues .

.338 Federal uploaded to KB 33 months ago by Nathan Foster .338 Federal uploaded to KB

If you have a chance guys, please read this one because its performance parameters are of interest. It does not matter whether you have any true interest in the .338 bore. Just have a read through and see how this cartridge leads to more understanding of the terminal ballistics picture. Note that my research differs a good deal from reviews you might read on the net, whether in published articles or forum threads. I spent a good amount of time getting my head around the strengths and weakness of..

True-Flite 35 Whelen / 358 barrels 33 months ago by Nathan Foster True-Flite 35 Whelen / 358 barrels

Hi Guys, I know there are other threads running but I wanted to put this in its own thread for posterity. True-Flite are now up and running with .358 caliber barrels. Grant put together a rifle over the past few days, a Winchester Model 70, rebarreled to .35 Whelen AI with a 24" barrel. Twist rate 1:12. Initial load work was performed yesterday 5/3/2016- just preliminary tests. The rifle gave up to 2730fps with the 225gr Sierra without fuss. Grant reports that the recoil of this load was fairly ..

Re: .303 and 8mm SST dropped from production 33 months ago by Nathan Foster Re: .303 and 8mm SST dropped from production

It is relative to the available force. It gets more difficult to swage down in big jumps, creating a need for a series of steps, otherwise you need a very heavy press (not reloading press). Bullet deformation is another factor. Spring back is another factor. Good options would be: 6.5 to .257 7mm to .270 .338 to 8mm .375 to 9.3 (Marty blogged his experiments with this on the forums a while back). There is a market for each of these, perhaps not large so again it may be best as a sideline for som..

Re-forming Brass to New Calibres 33 months ago by Paul Leverman Re-forming Brass to New Calibres

So as to not hijack a couple of the threads running here, I will start a new one regarding the forming of brass for different calibres. First question is when forming brass into the .308 Norma Magnum, what are you using for your parent case? From the interweb comes information stating that if you use .338WinMag brass, all you need to do is run it through the Norma f/l die and maybe ream or turn your neck diameters. But, the necks will be shorter than standard Norma magnum brass. If you use .300W..

Re: howa 1500 mag length 33 months ago by Martin Taylor Re: howa 1500 mag length

Thomas offered some good advice in looking at some of the old threads, much of this has been worked through to its conclusion withy great info offered. Seating to the lands is a folly in the 308w, totally unnecessary to achieve sub moa accuracy! 308's use jump to gain velocity as do many sammi spec cartridges. Address the rifle as per your book & Nathan has said, start at the heart of the problem. As we discuss on here, Harmonics can be a real pain in the ass, so minimise their effects. Long for..

Re: P-14 found in the bottom drawer 34 months ago by Grant Lovelock Re: P-14 found in the bottom drawer

Hey people, Grant here from TrueFlite For Thomas's action we are fitting a 1.240 diameter Knox diameter barrel to it..... this allows for nearly 1.5mm shoulder to mate against the receiver face... given that we do all our barrels up to 70ft pounds of torque, I cant see that deforming the shoulder at all. The thread is what stops the barrel from flying off the end, so from a safety point of view, that is covered. The shoulder ultimately sets the head space so once that shoulder has been set and c..

Re: BSA CF2 in 30-06, Rebarrel  to 35 Whelen ? 34 months ago by Nathan Foster Re: BSA CF2 in 30-06, Rebarrel to 35 Whelen ?

Tired posts. I get that. My post could do with correction too as I think about it. If you have the barrel in a barrel vice, it won't ring. You have to put the action wrench in the action, try with a long bar and can really only hit the bar when the force is loaded (two people) because things can fracture so easily (and then striking can be as bad as excessive heat). The trick is trying to get that tone to travel all the way to the barrel threads. Sometimes it all turns to hell no matter what you..

Re: BSA CF2 in 30-06, Rebarrel  to 35 Whelen ? 34 months ago by Warwick Marflitt Re: BSA CF2 in 30-06, Rebarrel to 35 Whelen ?

Sorry but :0 It doesn't work like that. Hit it like you mean it ! You watch a fencer or builder hitting in nails. They use a full swing to get the most kinetic energy into the hammer so that the nail gets driven into the wood! Swinging the hammer head hard and fast makes it really ring and sends a high energy Ping of vibration through the steel and the tapered pin just pops open.A heavy hammer just bruses and deforms the metal....... Make sure you leave the castle nut loose over the threads so t..

Re: P-14 found in the bottom drawer 34 months ago by Paul Leverman Re: P-14 found in the bottom drawer

In a previous conversation with one gunsmith, and from comments made here, I tried to find a barrel with a larger diameter, somewhere around the 1.325" that is "spec" for the P-14. But, as we all know about specs, they are open to interpretation. I did find one barrel maker in Alberta who can supply me with a 1.3" barrel, and everyone else can supply 1.250", of course. In talking to one supplier, he pulled some "drop-in" or "pre-fit" off the shelf and measured them while we were on the phone. It..

Re: two twist rates one barrel???? 34 months ago by Warwick Marflitt Re: two twist rates one barrel????

THREAD HIJACK sorry guys. The recoil will be horrendous. I am only using my own thoughts to analysis this and may be totally wrong! My thoughts are that as powder burns the pressure builds and recoil builds progressively. Similar to the hp torque curve of a petrol engine as rpm increases.. An electric motor makes maximum torque at zero rpm. So the rail gun will smash hard as it reacts to the input of energy. Then again its probably possible that it would fire a 10 grain bullet at 7,000 fps. Put ..

Hi All, I just finished bedding my .30 06 M700 with the Match Grade Bedding Compound. I don't have any experience with other kinds of epoxy or other kinds of alternatives. It took me two tries to get it (My mistakes not the product.)

Re: P-14 found in the bottom drawer 34 months ago by Paul Leverman Re: P-14 found in the bottom drawer

I see, says the blind man. It is not the threads. It is the shoulder diameter. Yes, this could be very problematic. Time to start looking for barrel makers.

Re: P-14 found in the bottom drawer 34 months ago by Paul Leverman Re: P-14 found in the bottom drawer

Thomas - re-reading your first response, and you mentioned that the barrel tenon was a problem in regards to the blank diameter. Do you have the diameter of your action threads? Mine measure out to the point where a standard 1.240" barrel will do just fine. I may be a little bit out on the numbers, but by calculation it seems that they are 1.125" X 10TPI, square threads.

I wish I could show you what I see, but unfortunately my optical equipment belongs on the ark. I'll try to describe it starting with the bolt. In comparing the marks on the P-14 lugs with lugs on my Ruger (that I know are lapped) they are very similar. Clean lines, extending into any pits that are present. Bright steel, but not a mirror-like gloss like hammered steel. The edges of the lugs show what I believe to be the original relief cuts. They are rough-ish and discoloured (black) inside the m..
