Can't go wrong with a TC Omega or Triumph. They cost more but the accuracy is there with the right bullet/powder match. The Encores and Prohunters are nice but too expensive in my opinion and may require another $50-200 to accurize them. (Mike Belm-hinge pins/trigger kit) Peek in on Gunbroker from time to time...they always have many TC's on the auction block. Knight's are good but unfortunatly out of business due to there inability to not keep pace with TC's marketing blitz. They are not out of business because of a poor product. Hats off to Knight for bringing the inline to market.
After much deliberation and opinions from other hunters with muzzleloader experience I chose the Savage ML BP at Cabela's . It isn't cheep but I should have it for life. Seems like a good decision so far. Check out Randy Wakeman's muzzloader reviews online (tons of good info ). Good Luck
