[QUOTE="SSG Graybush, post: 2859682, member: 115190"] Most bullet manufacturers set minimum fps for their bullets to perform/open up at 1500-1800 fps. Which is usually about 1000-1200 #'s of energy for non magnum rounds, more for mags with heavier bullets. The wound channel is caused by the bullets energy, not just its mushroom/pedals. The archery analysis would be like a full metal jacket, the animal is gonna die, just not bang flop. Minimal energy dump into the target. A 45 acp is like 475 #'s of energy at the muzzle. That 1300 yard shot with a 300 gr Berger EH at 1000 ft of altitude would still have ~2087 #'s of energy at ~1770 fps on impact. So those bullets should have fully opened and probably exited if broadside. People constantly argue about Long range shots, solids vs Bergers vs match bullets, etc. E=MC2. So increasing mass with less speed or less mass and more speed is equal. Until you add in the fact that in ballistics more mass usual increases bc. And the added bc efficiency allows that heavier mass to retain energy longer even if it starts slower. But saying it's not energy that kills is incorrect imo. Energy causes all that damage. Whether it's the bullet cutting a hole or organ damage around it. Here's 2 examples. Shot a button buck(thought it was a doe in low light) with a 450 BM at ~40 yards quartering hard away, hit a bit back just behind the ribs, exited mid ribs on the off side. The wound channel was so devastating that it literally blew the bottom of his stomach open about 5-6". That was energy not bullet sprawl. My 270 wsm causes so much damage am going to a solid (LRX) this year. Last doe I shot broadside at 100-120 yards hit center of lungs, straight through with a 2.5 inch exit, the energy was so much that it busted the diaphragm and split open her stomach putting contents everywhere.
