Any shooters with M1A's have a preferred factory 308 or 7.62x51 ammo? Just ordered one with a 22" N.M. Barrel, 1/11" twist rate.

I was thinking the Lake City 147 gr. cheap stuff would be ok for breaking it in but would like to try out the more premium stuff for precision/hunting and don't know where to start.

Mine seems to like most anything well enough. Poor accuracy with the surplus Winchester 7.62, but will shoot MOA with 150 grain core lockt hunting ammo.

I've been idly playing with some loads with 168 grain Matchking and Varget, 44 grain seemed to work OK last time.

Shooting 2 groups sub MOA @ 100, one just over 1/2" in my Standard (one 3 round group, one 4, it's all I had loaded at the time).

I'm still breaking mine in and have been shooting Atomic match ammo with fairly good results. I can get that in 100 round boxes. My neighbor gave me a couple of boxes of Federal Match, but I'm waiting until I have a scope setup before really getting into it.

I just purchased a case of Aquila 7.62x51 FMJBT. I'm going to run it through my Sig716 and HK91 before trying it in my M1A NM.

Just zeroed my LRB Standard M25 yesterday with 168 gr Federal Gold Metal Match in 308. I am no great shooter but am satisfied with group. Going to WY mule deer hunt in fall and may run into some long distance so I am planning on trying out the Nosler Accubond... it has high BC and supposed to expand even at low velocity at longer range. We will see.

I called Springfield Armory for some tech support when my new SOCOM CQB was having some reliability issues (which have since been worked out). They asked me if I had tried running any plain old commercial Winchester white box through it and told me that's what they use at the factory to function test their rifles. They also told me that's pretty much the only type of ammo that they guarantee will function in their rifles and that they don't recommend using surplus ammo. I thought that was odd, considering the military lineage of the design.

Great replies, glad to see a wide range of both premium and easy to find ammo producing good results. Gun is just shipping today so won't have pics up until next week.

Edit: I don't see a M1A club on the board, please post M1A pics if you so desire. I never realized how great looking they are. The AR world blinds you, seeing wood and steel is a nice change. I just couldn't make myself like the M&P 10 or other AR-10 patter rifles no matter how good the write-ups are about them.

Look forward to a range report.

If you plan on scoping it up and use a higher mount (mine is a Bassett machine) you way have fun funding a good cheek riser, I know I struggled for a few years funding the "right" fit between snug on the gun, the right height and length of pull (I tried an archangel chasis for a bit, but it's too long).

Recently I found this cheap thing that has worked really well so far, but who knows how durable it will end up being.

For factory ammo, for ringing out the best accuracy the M1A is capable of, Federal Gold Medal Match in either 168 gr or 175 grain, is the 'standard' by which all others are compared.

For when you start reloading for the M1A, here's a fantastic article.
I suggest going to page 12, and carefully read the inset/boxed information.
I get incredible accuracy from my (highly) accurized M1A with a load that's very close to what's listed in that box, using LC brass, H-4895, Sierra MatchKing 168 gr, and Win LR primers.
(I've had fantastic results with W-748 powder the Sierra 168s, also.)

That Federal Gold Match is some spendy stuff right there. I"ll stick to the ~.50¢ per round stuff. I'll leave all that gold plated stuff for you guys trying to wring out MOA or less.

I had an HK91 which is basically a truck. Solid and reliable Teutonic engineering. Wanted something a little more accurate that didn't beat the heck out of me and throw the brass a country mile and got the LWRC REPR. It is very accurate and has the 4 position gas valve, Geiselle trigger, Marksman stock, etc but really too heavy for use except off the bench. I wanted a lighter rifle with a shorter barrel, but a complete Sig 716 with 4 position gas valve was cheaper than just buying a 16" LWRC upper which now only has a 2 position gas valve. I liked the way the Sig handles and use it a lot.

Finally got around to shooting my M1 Garand and bought an M1A NM. Probably the least felt recoil of all my 308/7.62x51 rifles and very accurate. I plan on using it in the local three gun tournament (Rifle, shotgun, pistol). Now looking for a shorter barrel lighter version. Considering buying my brother's SOCCOM II.

I shot PMC Bronze 147 in mine, then reload the prepped cases with IMR 4895 and Nosler CC 168 bullets for more accuracy. Those cases have less internal capacity than LC btw. The PMC works great for plinking/breaking in. I currently buy LC cases and hand load most all ammo I fire through mine.
