Recently bought a CMP M1 Garand from 1945 and stupidly didn't take the offer for ammo when I bought it, completely forgetting about the shortage and how M1's generally can't shoot modern hunting loads. Everywhere, and I mean everywhere is sold out of 30-06. The CMP and other websites that sell specific 150 gr ball ammo for the M1 are sold out and have no idea when they'll be back in stock. Dunham's shelves were cleared of everything. At a small local gun shop I was able to get a single box of Wolf steel case 140 grain soft point for basically an arm and a leg. I know what most of you are immediately thinking, never shoot steel in anything. I understand that, but I'm really only going to be shooting the gun every once in a while, probably no more than 50 rounds a month, if that. I've read on other forums if you're not doing frequent shoots, shooting a lot of ammo, 2-gun, or historical shoots, then steel is fine if that's all you've got. I'm just worried about pressure, and if the M1 can handle it. I know you're not supposed to shoot heavy grain bullets through it but I don't know if a lighter grain of 140 helps the case for being able to shoot it. Can't seem to find any info about the type of powder used or amount, but do know that the muzzle velocity is 2,791 fps and muzzle energy is 2,421 ft-lbs. Again I don't know if those numbers are even relevant to whether or not the gun can handle it. Just hoping that there's someone on here that either shoots M1's, antique guns, knows load specs, or just any info that would be helpful.

Its excessive pressure at the gas port that can bend the oprod. The M1 was designed around powder with burn rates like 4895 / Varget. Slower burning powder will generate too high of pressure at the gas port, over-gassing the operating system.

Sort of unrelated. 110 or 125 grain bullets have become popular in competition because of the reduced recoil. There is a lot of data on line.

So do you think the ammo I bought would be fine? Biggest concern is safety and the gun busting apart in my hands

I've read into the gas plug and will probably get one, but do you think the ammo I bought would be safe without one?
There are some youtube videos of people shooting factory ammo out of Garands but over longer periods of time who knows if it might damage your gun. Other thing to consider is older the gun the weaker metal gets so possibility that op rod could get damaged. I have the military rounds for my Garand so never tried shooting factory ammo.

Hornady makes a 30 06 load for the M1.

Prolly be fine. Worse case scenario you bend the oprod. Nothing catastrophic. Go to youtube and look up oprod tilt test.
