300 win mag projectile selection

I'm trying to decide on the proper bullet for reloading and would like your feedback.
So far from the books and site i've gathered these as good options:

Hornady: 180gr SST, A-max 178gr, A-max 208gr
They all seem good up to 330lb >2600fps, and up to 700lb down to 1600fps (amax can be pushed to 1400fps with proper skill).

I also am geographically close to Matrix bullet distributor (Matrix 185gr VLD, 210gr VLD) but they are a bit more expensive than Hornady's options.

I'm expecting to encounter deer 180lb and up. And hopefully elk.
I'm not expecting to reach out close to 1000yds at this point.


It seems like the Hornady are very similar performance wise.
Should I just get whatever is easily available?
Any other recommendations?
Also, Would the 208gr going at a lower velocity than ~180gr make any real difference in Barrel wear?

Re: 300 win mag projectile selection
G'day Mike
I think any of those Hornady's will do the job up to Elk, the 208 A-max probably the best choice for Elk.

As for barrel wear, I don't think it would make much diff between the 180 or 208. I think powder burn would be similar. There's a fair bit of powder to burn in a 300wm, the throat will burn out a lot quicker if you let the barrel get hot.
Cheers
Bob

Re: 300 win mag projectile selection
208GN A-Max will do the lot!!!

Re: 300 win mag projectile selection
Yep another vote for the Amax 208 and they will hold up if you get in close & have to shoot your way out!

The Berger 215gr Hybrid has done extremely well at long range also. Definitely worth a look.

Re: 300 win mag projectile selection
I am a bit iffy on that still Jim. I wrote about it in the cartridges book as an option but have since noticed that any slight change in batch copper material will alter results. So it is something that has to be put through the preliminary home tests as mentioned in the book- per each pack of projectiles purchased.

The risk otherwise is pin hole wounding on light and large game alike.

Re: 300 win mag projectile selection
I have started testing those Jim and have found the batch l have very poor so far with the little testing l have done. But still need to take more animals to make a final call.
Pinhole wounding so far including solid bone hits, pinhole through lungs cross body.

I wanted to open up meplats but then the test parameters will have changed so will begrudgingly try a couple more......... but have already worked up 208's which ended up with the same charge weight in readiness.
l know these will cover all situations with the 300 because l have set up a mate using them with great effect both close and out far on Fallow, Sambar & Elk-Red Hybrids.

Re: 300 win mag projectile selection
Thx.

A couple more component Q's

1. Is the CCI/Federal "large rifle" primer suitable? They also have "match" and "magnum" options.

2. I'm not sure about powders. What is the recommended powder for the 208a-max? Can you give a brief explanation as well?

From what i can gather choices in the general area (from slowest to faster) are:
Hogdon Retumbo, H1000, IMR 7828, H4831sc, IMR4831

Re: 300 win mag projectile selection
1. Yes these are suitable. You will be getting up to around 74gr powder which is still within the realms of a standard primer if you want a slow burn. I tend to run the magnum primer in 24" barrels or in the very largest of cases such as the RUM's / Edge etc.

Manufacturers would probably recommend a magnum primer. Certainly a better option if you hunt sub zero temps.

Match is a good option if available- all helps with ES although the Federal primers are very uniform regardless.

2. H1000 / ADI 2217 is ideal.

Re: 300 win mag projectile selection
I wouldn't discount the matrix. I've used them on game ( no long shots) and they performed great. I've used them target shooting and they have been spectacular in 7 mm. If your not looking to push the amax's 1400 envelope the matrix is perfect. I just built a 300 wsm and bought 200 - 210 gr mmatrix bullets to play with.

Re: 300 win mag projectile selection
I was thinking more on Jeff's article with his experience with the 215. He's still batting a 1000. I think his longest elk shot is 1285 yds, but he is an extremely talented marksman.

Jim,
Where do I find "Jeff's article"?

Re: 300 win mag projectile selection
I think he is on one of the US long range forums Mike if l am thinking of the same post.

I purchased the 215's after reading his findings, which are very well documented and written up. l couldnt get any 208's in OZ for months so was looking for an option, but havent been able to repeat his results so far with the batch l have.

This may be the Jeff & story that Jim is refering to Mike (maybe!)

Re: 300 win mag projectile selection
Thx. Now I just have to find the stuff!
I'm figuring out the H1000 is all outa stock around here right now.
Most Hornady bullets too.

Lots of primer around though lol.

btw - I got my Rifle, gun shop told me there was no Rem Xmark trigger issue, what a joke. Naturally I checked with Rem, and it's on the recall list. I gave the manager a bit of a run down with that info.
I'm contacting the recall ppl and trying negotiate with them to replace with a 40x trigger for cheap instead (since they'll be doing the work anyway).
They say turn around time is only 2wks once they receive it.

From what I can see, rifle barrel, lugs, mag box look good! No tinkering need (yet).

Re: 300 win mag projectile selection
I use 208 Amax in an SPS SS 26" barrel. 74.0gr ADI 2225 (Retumbo) Norma brass Federal 210 (large rifle) primers. This gives me 2640 fps (0.6 MOA) and 1800 fps at 830 yards here in the tropics.
With this load the rifle is very mild kicking (not much more than my light weight mountain 7mm-08 with 162 Amax at 2740 fps) and a pleasure to shoot.
Hope this helps.

Re: 300 win mag projectile selection
Mike, I think that's the article. Another guy ( US sniper) shot a couple of coyotes at 1300 yds using the 215 Hybrid out of a 308! Again talent rules the roost! As for me, I'll stick with the Amax everyday. Has yet to disappoint me. Never lost a deer to the Amax. I wouldn't shoot anything less than a 208 gr in the 300. I think the whole purpose of a 300 win is to handle heavy projectiles. Heavy make the 300 shine!

Re: 300 win mag projectile selection
On Nathan's recommendation I run Amax 208 in a 27in barrel with 11in Twist in 700 semi custom @ 2815 fps seated close to the lands no pressure signs. This barrel has a long throat so bullets are seated way out in the case the action has an extended mag to allow enough clearance. Im getting .3 moa. I've just received some hotter loads so hoping for 2850+.

Recoil with an ASE suppressor is less than my .308

Re: 300 win mag projectile selection
I have been working with the 230gr bergers on a 300 win mag match chamber.
the problem is I cannot use the top performers 230gr match because I run out of OAL in the AI magazines and they do not seat well. But overall the 230gr tactical run great for extreme long range. If you look at the math the final trajectory is not too different from the lapua magnum y although doesn't have the same kind of punch (obviously). It can do 1500 yards before it goes transsonic and depeding on the pressure in front of you. I have never shot it that far though. For a budget bullet the 208 amax has been very consistent. ....My goal is also to inject a bit extra velocity so I am looking into a wildcat half way between the RUM and win mag and shorter so it can take the longest bullets, including solids.
