jim shockey did it with a front stuffer, and chuck adams did it with a bow, but has anyone taken all 29 species of north american big game with a milsurp? i doubt it. what would be the one rifle to use if you were to undertake such an adventure? i would say probably an 8MM mauser or a .30-06, but thats too common. lets say with a caliber other than .308 or .30-06. in that case i would probably go for a MN 91/30 with 215 gr bullets
