Mr Frank I currently have an #14(M24) and #13 CFW, my smith told me all of your barrels share the same liner and only differ at the shanks. Is this something you care to answer publicly?Also depends on the final contour of the barrel. Some will have more and some will not.
We've done 1.250" straight blanks in carbon fiber as an example. So vs a #4 sporter or the #13 Rem. Varmint contour your gonna have more carbon fiber on it.
