I picked up an old neck sizing die awhile ago and it works great. It is marked "Riverton Hght Gun Shop Seattle 88, WN Pat Pend" I'm using it for my 300 Sav. but it seems that it would be a universal die just by changing the sizing collet and expander ball. If anyone knows the history of these or if there is a source for sizing collets it would be apreciated






Thanks
