I have the original TC with 3 Bbl s, .22,357 with shot shell choke that you unscrew to shoot solid, and .44 mag X 14’’. Think I will try the .357 barrel and see how it shoots through the chrono with my cast boolits and powder. From what I saw on the vids you guys have honed your shooting to a fine art. Thanks for the videos and the info, rules etc. excellent.
