TC .54 White Mountain Carbine owners

[Prairieofthedog]

What is the barrel channel on a .54 TC White Mountain Carbine?I know the .50 is 15/16".I also heard the early .50 were 1 in 20 barrel twist,then they went to 1 in 38 twist.But according to TC's chart all White Mountain .54's are 1 in 48 barrel twist.I spent 2 hours searching the web and still don't know if the .54 White Mountain has a 1" barrel channel or 15/16".Thanks for any info.

54cal white mountain, 54cal hawken, and all calibers of renegades are 1in and for the most part are the infamous 1 in 48 twist.

you could measure it across the barrel flats with a caliper or even a good measuring tape
