BDS-THR right on the money. I just changed all my dies from 3 hole turret to 4 hole turret and had to adjust all dies for the new bullets received. I had to reduce my 9 mm OAL by .020 for the round to chamber from my previous bullets used. I learned this the hard way from my next to last bullet order, Did not do as BSR-THR stated and had inaccuracy/key-holing so all my efforts were a waste of time because of problems with the ammo not to mention the components used to make ammo that at best hit what you aimed at 50% of the time. I make my OAL as long as can be with the round chambering with the familiar sound of thunk. Just what I do.
