I'm going to get rid of my tc encore muzzloader here in the classfields, in hopes to fund a smokeless barrel for my custom rifle, it uses a zermatt arms origin action. I am currently looking at the pva smokeless prefits, but see they offer only 1:16 45 cal barrels, what twist rates and barrel lengths are you guys running on a smokeless 45 cal? Looking for recommendations on who to have do the work as well
