M1 ammo

I have an original military m1 sniper rifle and have shot factory rounds through it. I've been told that factory loads may damage the weapon. Does anybody have any experience with this? Thank you.

The M1 Garand operating system was designed around a certain gas pressure. Going above that gas pressure "can" damage the operating rod. This is why manuals like Hornady have a M1 Garand section with reloading data based on this.

Now, some people claim they can shoot regular hunting ammo through their M1 Garand without any issues. Regular hunting ammo, especially the newer stuff has higher gas pressures. You can get an adjustable gas plug for the M1 Garand which allows you to "bleed off" this higher gas pressure.

I have an M1 Garand, but I keep my loads within the recommended range. I have a FMJ load using IMR-4895 and 150gr or 168gr projectiles. I also worked up a hunting load (if they ever approve semi-auto) using 150gr soft point projectiles.

Several ammo makers make M1 Garand ammo that falls within the specs.

I see no reason to push things with my rifle. Why run the risk of damaging the rifle by shooting something outside the specs of the rifle?

You could also get a Schuster gas cylinder plug. This will vent excess pressure and keep the op rod from being bent.

Thanks for the information. I'm not going to shoot factory ammo out of it anymore. My 10 year old grandson loves to shoot it do I'll figure something out.

Federal-American Eagle makes new Garand safe ammo as do several other makers. Use that or get the adjustable gas plug as others have stated.

If you handload it helps (cheaper). Have to keep in mind there is a window of powders with the right burn rate. I settled on IMR 4064 (there are a couple others) for all my Garands Also founds it shoots best in just about all my U.S. and Brit Milsurps> as mentioned above, a number of load manuals list powders for Garands and there are a few ammo companies that make ammo specifically for Garands

Darn it, now you have me wanting to dust of a couple of mine. I also have one I had rebarrelled in 308 I still need to work with and tweek some loads for

Thanks USAF. I do reload and I'll check out my manuals and find the correct load. Have a range on my property so should be fun. Appreciate the information.
