a .308 small base die for years with shorter BR cases as well as 30-44's. It ends being pretty much like a borne out die when using shorter cases. I have often wished it was tighter. I'm gonna check to see if i trim a bit off the butt if it may work better. Pete
Pete, size a 308W case and check the shoulder and back end dimensions. Use those dimensions to figure the taper per inch in .001's. Then shorten the back end to pick up what you need. Don't be surprised if you need to shorten it more than you think. If it gets too short, the taper on a 308W die can get you into trouble by starting to hit the upper side of the BR length cases.

Pete, if you have or can borrow a 45 ACP die to try, give the cases a pass in that. It sizes the base and doesn't get after the sides of the case. A carbide version works great. -Al
