Going to have a barrel re bored from a .50 cal to .54 cal. It's a T/C Renegade with a 27" barrel. What would be a good twist be for round ball?
Get the slowest twist you can for the rebore 1:60 but depth of rifling could be more important. Narrow lands and shallow grooves .006-.010. so you dont rip patches up. Number of grooves comes into play as well but nothing that is not easy to find for decision making on the web. You asked for a RB barrel only.
Dropped off the barrel today going up to .54 cal.with 1:60 twist.
