Does anyone know what the twist is in the white mountain carbine?
If anyone has one in 54 cal, what bullet,load combination preforms best that you found.
Thanks in advance !

I'm pretty sure that the 50's had a fast twist barrel. 1/20 ? Maybe.
I didn't know they made one in 54 caliber.

Ive got a .50 wmc but still havent checked the twist. I thought it was 1:24”. I had a .45 wmc and it was a 1:20” twist. Never have seen a .54

I've read 1:38, 1:20 and 1:48.
I'm thinking the 54 is either 1:38 or 1:48.
I keep getting different results with measuring with the ramrod. Really like the size of it. It shoots round balls pretty decent out to 60 yards. Was going try a conical bullet and was curious if anyone who has one has found a bullet that works good for them before ordering
