OK, my go to muzzleloader is a 1992 vintage TC Thunderhawk, yeah its ugly, kinda outdated but shoots like a house a fire, have taken several deer beyound 200 yards, farthest was 267. On a good day 3 TC 250 gr shockwaves will blow one large ragged hole in a 100 yard target. was affraid I couldn't get parts for it if the need should arise so last year I bought a like new/used one for 225.00.
a couple pics
the first day I hunted with it, one buck fell at 30 yards, the other at 110

the next year, I missed this buck running on thur morn, took him fri morn

This buck was shot the last day of season a couple years ago at 208 yards, DRT

anyway look around you can buy these guns for cheap, and their replacement model the diamond back is cheap as well. the thunderhawks come standard with a timney trigger.
