Hello All, I'm new to the forum and after reading through some topics, this is awesome! My question is, I just had my M1A rebuilt to a M21. Looking for reloading info for hunting and comp shooting. Any info is appreciated to get me started.

Get a Sierra reloading manual. The M1A requires a medium burn powder for proper gas port presure. The Sierra Maual explains this well.

I believe it might be the Nosler book which has a separate section for M14 types.

Shop around until you find one that does.

My numbers from QuickLOAD indicate that, contrary to some other opinions, Varget is not too slow for the M14 gas system, so long as you keep velocities of 175s below 2650 (or was it 2600? 4064 shoots 'em tighter for me and with lower ES and sd, so I pretty much quit trying with Varget a few months ago).

RE-15 can safely work, too.

With both, the limiting factor is not the chamber pressure, but the port pressure (max spec is 14,500 psi). The end result in about 100 fps slower than a chamber-pressure safe load for a bolt gun, and predicted pressures in the mid 50,000s rather than being on the ragged edge of 60K.

My op rod speeds and resulting ejection pattern are consistent with these predictions.

Hey Raider, Did you get it back already? You better get a bunch of ammo loaded for it so I can play with it when I get down there this summer. PS VARGET

By the way...Welcome Aboard SGT.MAJOR !!!! Thanks for your service to our country for the last 31 years! And Thanks for teaching me not to step on my johnson for four of those! Semper FI

The new Hornady manual has a 7.62 Service Rifle section as well as 5.62 and M1 Garand.
 
Re: Reloading data for hunting and Comp for M1A

The AMAX bullets work good for me for hunting and targets.
 
Re: Reloading data for hunting and Comp for M1A

Thanks Guys, great information. usmcsniperone...those were great days, humping around the old bolt gun (not for the occasional coyote that would spy on our patrol!). Looking forward to your visit!
 
Re: Reloading data for hunting and Comp for M1A

A really good load for me in my match grade M1A has been 38 grains of IMR 4895 and 168SMK projo's.
 
Re: Reloading data for hunting and Comp for M1A

My LRB M-25's favorite load consists of 168 SMK's at 2575fps.
I use LC brass, surplus 4895 and CCI-34 primers.
 
Re: Reloading data for hunting and Comp for M1A

I use 43.5 GR's of Winchester 748(2550-2600fps) with 168 AMAX or SMK for shooting paper then I switch to Barnes 168 TTSX, Hornady 165 Bonded, or Nosler 165 Accubond for Hunting. You will have to re-zero but they are pretty close. AMAX can be used for hunting but it is a thin casing and can break apart. I like going to Barnes for Hunting bullets as that is their specialty.
 
Re: Reloading data for hunting and Comp for M1A

Nosler has a 168gr. bt back that up with 41 gr or 41.5 gr of imr 4895 and you can shoot matches and hunt with it.
 
Re: Reloading data for hunting and Comp for M1A

Guy at my work swears by 748 - 44 in win brass, 42.5 in military with 168SMK. He's old, fat, and bald, so he has to know what he's talking about.

edit: that would be a target load, for hunting I would use a 165 soft point and load a grain or two lighter if it's a flat base.
