I bought one of those new fangled inline shotgun primer muzzleloaders a few years back. My TC Hawken has collected dust since then.
So much easier to clean and lighter than my Hawken. Really nice that I can put a scope on it. Accuracy is the same between the two since my Hawken was a fast twist one, so it was designed for maxiballs and sabots, accuracy sucked with round balls. I do like that my MZL is designed to have a scope and I'd feel pretty confortable shooting at deer or larger sized critter out to 150 yards, it really drops after that.
Here is a pic of my CVA Optima with a 2-7x35 burris on it. Bought both on sale so I have less than $400 in the combo. I'd buy it again in a heartbeat.
