Got out and ran a few ammo tests this morning. Atomic was a bit slower than any of the others at 12'.
Ran 10 rounds of each through my brandy new XM21 with Med weight 20.5 inch Bula Defense barrel cut and target crowned. All were 1moa or better at 100yds. Temp 40 deg.

Results: Atomic 2423
175 GMM 2526
XM118LR 2500
ZQI 2742

Default Ammo for M1A

LC 7.62X52 FMJ circa 2015, 2016.
PPU 7.62X51 FMJ, recent manufacture.

Federal .308 Win. 168 grn. BTHP Match (available from CMP)
Made for the M-1A, American Eagle 7.62x51 168 grn. OTM BTHP (available from CMP)

I have also fired other factory ammo, Perfecta .308 147 grn. FMJ, PMC 150 grn. .308 Win 150 grn. PSP for example, but I used a Schuster over-bored gas plug. I do not use it with any of the other ammo, but I find that it is sometimes difficult to find out specifications about all types of factory .308 ammo.

A good ammo website to use, among others is www.sgammo.com, they sell a lot of different ammo suitable for the M1-A and I have had good luck purchasing from them.

Go on over to the M14forum and you will find a wealth of knowledge there about different ammunition that is suitable for the M1-A.

As a side note, I do not shoot steel cased ammunition of any kind in my M1-A's.

HTH.


Thanks for quick response and ammo info. I have Mosin Nagant and can only find steel case Russ ammo. I had already decided against steel in any of my other guns. Some initial ammo research had me leaning toward Previ or LC. One entry I read talked about how "hot" Hertinberg ammo was so it started me wondering if it would cause problems with internals of rifle over time. Thanks again for the info.

My standard load out to 300yds is the Speer 125gr TNT, 44.2grs BenchMark, CCI 34 primer, any brass, OAL 2.666". Powder charge can be reduced 2.0grs for 100-200 yd matches. The Sierra handloading book lists standard loads for M14 types as do many other manuals. I rarely shoot non handloaded ammo, but the HXP (7.62MM) available a year or two past is, excellent. Good Shooting. ..

Where did you hear that? I do not believe that is an issue with the M1A/M14 family of rifles.

Currently I am using ZQ1 (WalMart), PPU in both 7.62 and .308, and Win 7.62 white box in my M1A and Fulton M14 receiver with mostly my GI parts. Both rifles shoot better than I can with this ammo. Also, I am currently using this ammo in my 2 M1 Navy mod 2s built on CMP barreled receivers with no issues.

There is some Atomic brand ammo that is too hot so avoid that brand.

My comment about pressure and possible rifle damage was prompted by reading one of the ammo suppliers posts about the difference between military 7.62 NATO and commercial .308 Win loads. It discussed the higher pressures generated by .308 ammo because it is generally loaded with different propellant and heavier bullets intended to take large game animals at distance. So, I ******-u-me that it would cause very rapid and hard cycling which might cause damage to my rifle similar to possible op rod failure in the Garand by shooting ammo not loaded to M1 specs. I did not want to bend a brand new rifle the first time out by shooting the wrong ammo in it. Appreciate your response, getting some VG info.

I can hand load if necessary, but will need some 7.62/.308 brass to get started. Appreciate the info.

II would love to get some HXP, which I shoot in my Garand's, but have not seen any so far in my internet ammo searches. But will keep looking. Right now am leaning toward new PPU or LC. Once I have some brass might try some hand loads.

Great info Art.

Not too long ago on the ammo page the Atomic ammo was discussed in depth and there was an opinion that it was not safe to shoot based on a few posters' serious failures. Have you read any of that thread?

Looking at the velocities you posted the Atomic is not overloaded.

Opinion?

Thanks, Rich

Between the much more efficient cartridge and the relocation of the gas system, the much exaggerated sensitivity of the M1 is virtually nonexistent in the M14 setup. The M1A from Springfield Armory, Inc., is a cast, attempted clone thereof.

Ditto the alleged bullet weight issues.

Not heavy at all and very consistent velocities, at least with what I fired this morning.
A lot depends on the rifle, as you know. All of my M-14 rifles have .308 type chambers headspaced to 1.632 - 1.633 with the extra throat cut for XM118. I am sure if you were to jamb the stuff in one of the 1.630 chambers some think is prefered, you might run into a problem.
Like anything else Rich, you need to know your tools and be aware of how they function.
As far as posters somewhere else having a problem, I did not see any of that.
There are some that have a problem with anything.

Would rather have had the forged rifle but it was a question of $$$$$$ v cost of weapon! I figured a M1A or not rifle at all! :>(
