Shot a buck with my 30-06 last season - perfect heart/lung shot, turned everything to mush, but he still ran 400 yards in 10 seconds before dropping. These animals are just tough! Got me thinking about ballistics though. A .22-250 and .45-70 have similar energy on paper, but one's for coyotes and the other drops grizzlies. Energy formulas overweight velocity - if speed killed everything, we'd all be using .17 magnums at 5000 FPS! Big bore cartridges don't need to expand like smaller rounds do. They start big and hit hard. What's your take on energy vs bullet diameter for hunting effectiveness? #hunting #Ballistics #HuntingAmmo
