I know that you shouldn't shoot ammo through the M1 Garand above 150 grains, however I have no idea if this ammo is above 150 grains. Does anyone know if it's good to run through my rifle? I also thought that the Germans and Japanese didn't have body armor in WW2, so does anyone know what it was used for? Thanks for your help in advance.
