I think I very much prefer the NEF. TC has alwasy had difficulty with screw and ovetail depths - getting them too deep is a common TC problem- modern or muzzleloading guns allthe way back to 1970. Seems things haven't changed much with them. The warrantees are great - goos thing cause almost all their guns need warrantee work. I guess I seem to not like TC very much. Sorry - just my opinion, of course.
