If you're a raw bone rookie, get a decent muzzleloader, read somewhere online what someone else is using, drop 2 or 3 pyrodex pellets (depends on your gun and load!!!!!) and cram some bullet over it, or sabot round.
You should really find someone that has one for them to teach you how to load and fire it and stuff. But you can learn online.
My friend swears by Knight. Synthetic, scoped, with sabots. We're probably sighting it in tomorrow.
Others I know swear by traditional style sidehammer muzzleloaders with round balls.
Some states only allow sidehammer guns for hunting I think.
Either can be MUCH MORE accurate than you would think. Its all in how consistently you load it. They will easily outshoot an AK, I wouldn't want to do any MOUT with a smokepole though.
Inlines will be more weather proof, especially if they are 209 primer fired instead of percussion cap fired.
There is something to be said about a big, heavy, slow moving piece of soft lead hitting a deer. A roundball will do a lot more damage than most people think.
