I have some recent build (still NIB)......within the last 5 years, Springfields, an M1 Garand and an M1A SS loaded, and am curious about ammo. I have never shot either rifle, obviously (if NIB). I wanted some REAL battle rifles. You know...I could drag behind the truck till I get there and the still work .

I suspect either M1 would be a better, more reliable choice of "go to/bug out/only taking one" long gun than my AR10 or AR15s (not that they have been unreliable, but too many buddies in 'Nam with too many stories about the very poor timing of their failures and malfunctions).
My question;
I read somewhere that the Garand and M1A were not designed to shoot commercial ammo?? only military ammo?
I do know the M1A specified it was built for 168gr ammo. I did not see any reference to commercial ammo vs mil spec ammo.
I have only found 7.62x51 military in 150gr. available. My doubts about the ammo is one of the reasons I haven't ever fired the rifles. My worry being about the balance of the spring pressures in the semi-autos for the bullet weight/powder load.
I do have bolt actions in both those calibers and have plenty of commercial deer hunting ammo for each in 150gr ....also 180gr and 220gr in 30.06.
I do know that the standard military M2 ball for the Garand in 30.06 is 150gr also, but have heard the powders are different in commercial causing much high chamber pressures and that the Garands would break.
Any of you old timers or riflemen know of or have shot regular .308 in the M1A or regular 30.06 in their Garand? Any Problems?
