I have 6.5 creedmoor dies. Redding compete ton type 's bushing 3 die set. I just received a new 6.5 Bartlien #14 contour bbl. The gunsmith said I can use the 6.5 creedmoor dies BUT, I called Redding and they said they may work but not ideal. I called WhI'd den gun works and they said it wouldn't size the base. Anybody have a correct as newer to this?
