Hello all. I'm looking for some info. I'm trying to find out who can spin a 7-300 wby barrel large Shank for me. Looking to do a light palma ,or heavy sporter at 27" or better. I know shilen can but I had a bad experience with there barrels. Not slamming them just my experience with barrels that were made up by my gunsmith for my Winchesters. I would love to have a criterion but they can't do it . What does everyone think of a pacnor or a 4d. I think they both make them. I appreciate all your info
