[QUOTE="Buffalobob, post: 126295, member: 8"] I'm skeered to ask why you didn't just buy 338-378 Wby in the first place. OK. couple of things to look for 1 watch out for split necks. If it looks quesionalbe throw it away. 2. The radius will be different on the shoulders and you will need a mild load to blow out the shoulders correctly. 3. The double radius shoulder is designed for gas flow purposes, not strength. so when you begin to apply a lot of vertical pressure from the die you can actually push the neck right down into the case. That's all I know and I have never attempted to do what you are doing. [/QUOTE]
