First off what restrictions if any is there for muzzleloader hunting in your State? Are there restrictions on ignition systems, scopes, projectiles, or anything? Also what are you interested in using the rifle for? Deer and targets? Elk some day? All of this might make a difference.

Are you interested in an inline rifle or a traditional rifle? Are you opposed to owning a used rifle because there are some good deals on used rifles. Are you interested in any one kind of action over another? ie; bolt, striker/hammer, break open...

The NEF Sidekick is a good rifle from all the posts I have read on it. There are also some great traditional rifles on auction sites that are new in the box that can be had for a reasonable price.
