What is the appropriate ammo....?

[.45s r best]

Thanks for the input! Yes, 150 grain is my favorite bullet weight for target shooting. I shoot my Garand on a regular basis and the M1 ammo I use is 150 grain. When I cannot get American Eagle M1 30-06, I shoot Winchester 150 grain with an adjustable gas plug. I most likely will take the ol' '03 out to the range!
