From what I’ve been told, it is the bullet design, not speed that will create havoc on an animal.
My utmost preference would be to have the fast designed bullet, with a design that will mushroom on impact. My preferred (I’m old school) round is a “boat tail soft point”. This round creates a very flat trajectory, however will mushroom very nice on impact. I know that there are new designs out there that will perform much better “today”, but I haven’t had the chance or need to experiment with them yet.
Just a note, (again, I’m not bragging, just stating trajectory facts). I’ve shot a .308, 800 meters and hit a 18″ square target with open sites. I also connected with that same size target @ 400, 450, 500, 550, 600, 650, 700, & 750 meters. Again, this is just with a simple .308 caliber round. The round had nothing special done to it. It was all in the barrel.
Mossydan; I do hear what your saying about the moose hunting. My dad pumped 4 .308 rounds into a big bull before it dropped. He pumped the rounds one after another. All 4 rounds went into the “boiler room”.
Another true story was when my uncle went on a elk hunt in Colorado back in the 70s. He was using a .300 H&H mag. Across the valley, stood a big bull 400+ yards. The guide, who was glassing the bull, told my uncle to take him. My uncle shot, the bull shook it off and just stood there. So my uncle shot again……no movement from the bull. He shot again……..the bull didn’t even twitch. With him getting angry, and the guide yelling……..he took one more shot. the bull still didn’t move………….Then the guide told him to stop…………..They sneaked up on the bull and when he shot it the first time, hit it perfect in the spine, killing the animal. The antlers got caught up in a tree behind the bull. My uncle had three more shots in the chest, leaving an exit wound about the size of a basketball. The bull was dead and didn’t move, so when my uncle kept shooting, it looked like he kept missing…….
