Wanted to keep shooting round balls in our Traditions st louis hawken rifles so I purchased 2 CVA 54cal barrels for my dad and I. The drums just needed a little minor adjustment, then the barrel tenon relocated & dovetail cut. My barrel is currently in the browning box and once its done, I'll get my dads barrel prepped and into the box as well. Due to lack of crown on this barrel, I ended up LIGHTLY coning the muzzle to knock the rifling down at the end for a smooth clean, cut free transfer when loading the patched ball. The recovered patches looked excellent as well.
