45 Cal.
I have had a Lyman Trade Rifle, 50 cal. 1/48 twist since 2001. Could never get good groups even after lapping the barrel because it kept cutting patches. I shoot round balls and I feel the 1 in 48 is to fast for roundball. I just got my barrel back from Bobby Hoyt and had it bored out to .540 cal., .011 groove and 1 in 60 twist. What a difference in accuracy! I went from 6 inch groups at 50 yards to 1 1/2 to 2 groups at 50. My main point here is to decide what style of ammo you are going to use. For roundball go with a 1 in 60 or slower, for conical go with a much faster twist, maybe 1 in 32 or faster. My Lyman has always gone off first shot as long as I did my part with sharp flints and dry powder. I tried to order a kit from Chambers but things just didn't work out for me. Maybe I'll try again some other time because I would like the challenge of putting together a quality kit that requires alot of work.
