The Ron Smith barrel I have is .338" x .330" and was marked 14.6 x 30". My friend and I spent the better part of the day trying to measure the twist without success so we decided it was whatever Mr. Smith said it was.

I use the same 220gr Pope bullet muzzle-loading or breech-loading.
On the .32 Pope's I have owned I used the Pope 200gr bullet for both muzzle-loading and breech-loading.
