Go with the NEF. If you decide later on that you want to shoot smokeless powder there is a company that makes a smokeless barrel for the NEF. I am thinking about trying that after I get over the expense of my last purchase which was a flintlock. (Seems like I sure cover the whole range of muzzleloading since getting bit by the bug). Forgot to add: I have had good results with Simmons shotgun scopes on my muzzleloaders. I recommend using steel rings if possible or very strong aluminum ones with more than two retaining screws. I usually use a Weaver type rail mount.
