Well i had 3 muzzleloaders and all 3 had a 1 in 48 and my brother had a T/C with a 1 in 48 and we both spent over a $200.00 in patchs balls sabots and conicals and powders. These guns shot like !@#$.. I went out and bought a Knight with a 1 in 28 twist and my gun will shot 1.5in groups at 100 yards. I then went out and bought a Lyman great plains rifle with a 1 in 60 twist and at 75 yards it will put a patched round ball in a 2in cirlce every shot. Like i said i'm know expert but i have read a book or two on muzzleloaders. If your happy with paper plate size groups at 40 yards then i highly recomend a T/C with a 1 in 48...
