Home Forums Hunting & Shooting Hunter's Campfire How much energy is needed to kill an elk down range?

I managed to drop a 650 lb, 11 yr old cow elk, with a 165 grain 30 cal Ballistic tip, at 175yds that left the muzzle at 2250 fps.

destroyed both lungs, cut the esophagus and blew up the upper half of its liver.

it was at a dead run and made it another 60 yds or so, and then collapsed.

don't think we were dealing with big energy figures there..
