I agree! This is part of the problem and the solution to that problem, matching a bullet to the purpose. The game your shooting (genetic makeup), the actual shot placement on that game, the impact velocity, etc-etc all make a difference on a bullet's terminal performance. The same type of bullet in different calibers and weight for caliber make a difference. Many will say the barrel twist rate comes in to play, or even how the rifling engraves into the bullet jacket, and on & on. Lots to consider, you have to do your homework and make your best educated decision. I say don't just grab a bullet and go. Read too many folks saying "it worked on elk, so it's gotta work on deer" or vise versa. Or if it'll expand at 800 yards it should do a great job at 50. How about this, just shoot Hammer bullets and be done with it! Threw you a little plug in there Steve!Do your research and pick a bullet designed for the cartridge, distance and game you want to shoot.
