I need input from you muzzleloader guys! I'm thinking about getting my first muzzleloader, I have the brand and model picked out but can't decide on the caliber.

I've heard from some that the .45 has higher volocity and plenty of knock down for deer and elk? I need some opinions on the knock down for elk with the .45. I understand in some states the .45 is not permitted for big game so I would have to get a .50 eventualy if I went with the .45. Another pro with the .45 is the rifle would be lighter.

Will the .45 shoot more accurate than the .50 at longer distances?

Any input is appreciated, thanks
