I've only had 1 muzzle loader and that's my 45 caliber T/C G2 Contender. I've had it about 8 or 9 years and taken a few deer with it but still haven't found a load I like. I'm still experimenting with it. 40 yards is the furthest I've trusted it on deer so far. It's been awhile since I've had it out. I've been concentrating on centerfire guns the last couple years and just haven't done much with it. I've used 3 different kinds of powders and 4 or 5 different bullets and different charges and just can't get good groups with it.I've gotten a little discouraged with it actually.
