Re: m1 garand ammo
DO NOT get ammo at Walmart for an M1!!!!!!!
The M1 requires specific port pressures to prevent damage to the operating rod. You do not want to bend an op rod unless you have a 100 or so bucks burning a hole in your pocket. You'll know when you bend one...the gun will lock up, literally, as the rod will not slide in its channel any longer.
The M1 is regulated to shoot M2 Ball ammo. ALL hunting and sporting ammo is just too hot for the M1's oprod. You MIGHT get away with on a limited basis, but regular feeding of hunting ammo will bend it.
The best thing to do is get milsurp M2 Ball. CMP sells this, and you can find it at gunshows and online.
Failing that, Hornady makes M1-compatible match ammo, but it is not even in the same time zone as "cost effective".
I reload for it, and you can go that route, too, but you need to work within specific powders, bullet weights, and charge weights.
Look up a Schuster adjustable gas plug. This replaces the lock screw on the gas cylinder plug and will let you shoot about anything in the M1, as you can adjust it to "buffer" the force imparted on the rod. Last I looked they ran about $30 before shipping. Google will lead you to them. I have never used one, but the CMP forum guys love them, and that tells me all I need to know, as those guys forget more about M1's than I'll ever know.
Where are you getting your M1 from? (Just curious...)
Depending on where you in SWPA, you probably don't have a terrible long drive to Port Clinton, OH. That's where the CMP's North Store is located. There you can get M2 Ball aplenty, see about as many M1's as you can imagine, and get advice from folks who know those rifles inside, outside, and backwards.
If you were on this side of the state, I'd give you a couple boxes of M2 from my stock to help you get started....but I'm on the other side of PA from you.
