I've killed a pile of critters, mostly caribou with bullets ranging from the 100 XFB to the 170 Pro-Hunter. Mostly the bullets I've used have been around 140 grains with the Hornady SP and Barnes XFB doing much of the killing. Moose die readily by the capability of the little 308 cased 7mm.

Sometimes, the air you 'let in'matters less than the air you 'let out'.
