Too many options out there! Lol! All comes down to what "style" interests you and how much $ you want to put into it. Regs will help decide what you'd like where you plan on using it. Here in IL and WI, it only has to be a front stuffer to qualify as a muzzleloader. Any kind of ignition system, scoped, whatever. All good as long as it loads through the muzzle and meets a bore diameter requirement. Been a long time since I hunted MN, no longer remember their regs, my BIL has hunting property over by Askov.
If you could narrow it down some, would/could go a long way with recommendations.
