RE: T/C Scout Rate of twist ?
I don't have any direct knowledge, Ozone, but have been researching the Scout carbine as I was interested in one being offered on Gunbroker.
The seller listed the .50 carbine has having the 1-in-20" twist. This agrees with what Sam Fadala listed as the twist of a .50 carbine he tested in his first Blackpowder Loading Manual. This is the same twist he shows as being used in the .50 White Mountain Carbine.
InS. Fadala'stesting and in the case of forum comments from Scout owners, the fast twist .50 carbine is supposed to beextremely accurate with conicals; but my informationis all second hand.
For some reason, T/C seemed to favor a very fast twist with their carbine length barrels and got good results from them. Why this wasn't carried into the longer rifle barrels is a mystery to me.
FWIW
