Recommended ammo to use in the M1 Garand?

Never once in 40 years have I ever seen nor heard of any 150 gr commercial ammo damaging any rifle until there was an Internet. Despite unproven Internet reports. Literally millions of rounds of commercial hunting ammo has been fired out of M1 Rifles for eons with zero damage.
JC demonstrated, more like proved critics wrong, the strength of the rifle with up to 120,000 PSI blue pill loads(70,000 psi being a standard BP load). The only damage was a cracked left locking lug. The same rifle went on to be fired, with no parts changed or damaged, using a further 5,000 rounds of standard service ammo.
Hand load formulas that imitate 1936ish ballistic technology that get called .30 M2 ammo. No such thing as .30 M2 ammo until 1940. The rifle was designed to use and all testing was done with .30 M1 ammo with its 174.5 grain bullet at 2640 FPS. Later upped to 2800 fps to match the ballistics of .30 AP ammo with its 168 grain bullet. Any ammo in that range(2600 to 2800 fps) will be fine.

The biggest error here (among the herd) is the misapplication of the information provided. The point of a proof load is to test ultimate fail strength of the action not long term cycle reliability and lifespan. The blue pill would crack lugs....but heavy bullets or even light bullets over a slow burning powder (which they didn't have at the time of these tests) WILL bend op rods. The pressure at the gas port will be very much higher then that generated even by said proof loads, which where constructed with a very FAST burning powder. Given the value these rifles currently have on the market, maybe you should refrain from posting information that will damage them. I apparently have seen more then you, as I have seen damaged rifles from shooting over the counter ammo.
 
I will stand with approved ammo for my JRA Garand M1 to come, small price to protect a great rifle... JP.
