So I read an article tonight in Deer and Deer hunting magazine about muzzleloaders...specifically the .45 vs. .50 cal...and he basically made the point that other than the .50 being legal in all us states, better for really big game, like Grizzlies, and being the most easy to get, that the .45 is the superior caliber because of higher velocity and energy, and that it was a better long range accuracy round with less drop.
If this is true then why aren't more people using .45's and not .50? And also why are .50's so much more popular?
