Both of my TC Hawkens have Green Mountain replacement barrels
Austinhuntman. The .50 has a 1:28 twist that I shoot with sabots, and the .58 has a 1:70 twist that shoots patched balls into tight groups.
Each one is my favorite rifle when I'm shooting it. But then, every muzzleloader I own turns out to be my favorite at the time I'm shooting it.
