hello all lurked here a couple years not real internet guru type. why does the 300 338 smk do so much damage to game. my 50 bmg doesnt touch what a 300smk will do at 2850 muzzle velocity. with impact velocity ranging from 2800 to 2000 this bullet to conventional thinking would plow thru and thats it. i've shot or seen shot 15 deer since i got this gun from 250 to 1250 and it always amazes me. any explanations?
