like WisnonsinDeer said, i would look at the CVA lineup, or traditions. they both have very very nice entry level muzzle loaders. CVA has the wolf, and now its even nicer than before due to the QRBP(Quick Release Breech Plug). reportedly you can remove the breech plug with no tools at all. they have a video of them shooting the muzzle loader about 25 times or so(cant remember exactly) without any cleaning and they pulled the plug by hand. and traditions has the buckstalker, which i am actually looking into buying when i have the money saved up(wife and two kids take priority over my hobbies). they can both be had for around $200. if youre like me, you will probabyl look at the bare model and buy your own scope, or go iron sights(i havent decided yet). or you can buy the pre set up kit and have the scope and sling with it. the most expensive bauckstalker i saw at cabelas was $369.00(the kit), the cheapest was $169.00(bare).
