Thanks for clarifying that Raven. Hey,do you sleeve barrels? I have a nice Belgian Centennial Centaure with a barrel too shallow in the grooves to shoot right. A wide spot right at the end of the barrel too. Shows in the fouling laying in that spot.
I have a piece of Sharps 44/77 barrel liner that's exactly the same groove and lands diameter of a Centaure 1860 Army Colt. No lathe to turn it to exactly .500 inch to sleeve the old barrel. No piloted drills the right size to open up the barrel either. Fixed income VA makes it hard to save up fer tools. R.L.Millington did one the same already. Came out nice.
The twist in the 44/77 Sharps barrel liner is 1-20 and faster than the 1-32 the Centaure has.
Some Centaure 1860 Army Colts have a faster twist like 1-18 also. The faster twist is accurate with the round balls.
