If you are proficient at muzzleloading ( more than just the trigger squeezin') then go ahead and go for it. I haven't carried a shotty in the field in 3 years, save one lousy day when my dad talked me into taking his 1100 out. I lost a chance at a shot that day, because I was unfamiliar with the gun. I hadn't shot it in years.
The reason I ask if you are proficient is not a personal doubt on you. So please take no offense. I just know alot of hunters who took up frontstuffin' to extend the hunting season. These guys didn't take the time to take care of their guns the right way. These inlines look, for the most part, like cartridge guns, and the hunters expected them to function like cartridge guns, too. They almost all used two pyrodex pellets and whatever the guy behind the counter at the gunshop said would kill deer wherever you hit 'em. (And we all know how smart gunshop counter folk are, don't we?) It's funny how 6" 50 yard groups from a smoothbore deer barrel on a shotgun can make 4" 50 yard groups out of a muzzleloader look good to some. They about crapped when they saw me shoot 1 1/2 inch groups out of my Omega... at 100 yards... with an large aperature sight.
If you are going to take the ML instead of a shotty, realize that ML's aren't magical deer slayers all by themselves. It takes a dedicated individual to make the most of a muzzleloader's ability, and to know the drawbacks. 200 yards can be reached with a modern .45 or .50 caliber gun, but it takes lots of practice to do it regularly. 200 yards is a long ways, even for a 30-06. Know where you're gun prints at 50 to 200 yards, in 25 yard increments. Write it down and tape it to your stock so you have it to reference for those long shots. Play with loads, find one that shines.
One shot- one kill!
