If you are looking at getting one I would go with an inline.

My dad hunts with the old traditional style and it cost him a chance at a big buck last year. He was in a blind and the buck was 15 yards away with a perfect broad side shot. However, when he pulled the trigger it made a pop sound and nothing happened. The buck didn't even take off, and of course myfather didn't have any other ammo.[:@]

Apparently, the nipple or something got a little dirty and that's what he attributed it to.

With that said, I love muzzleloader season. It really is like a middle ground between rifle and archery with regard to hunting distance.
