I hear folks talking about bumping the shoulder back one or two thousandths. How can I do that with a FL die? I`m tired of FL resizing and hopefully I can get a little more accuracy and life from my cases.
Watch this video:
Thats a great point.You will find also if you mix your cases up on how many times fired your bump will be all over the place due to work hardening
You can dispense with the water. Just drop them on a metal surface and let air cool.I anneal my cases by putting them in a shallow pan of water and using a propane torch heating the top of the case a dull red and tipping them over in the water. It makes resizing them much easier is there a better way?
A set of shims can help. Put a .001 or .002 on top of the shell holder and screw the die down on top of them till it is tight. Tighten the lock ring, size the case, and then measure and see if you get the desired result. You may want to start with an annealed case to prevent any brass spring back. To prevent case stretching keep the sides of the case well lubed.I hear folks talking about bumping the shoulder back one or two thousandths. How can I do that with a FL die?

To add to this point I do find there is the odd case that doesn't fully fire form the same as the rest resulting in a longer shoulder dimension after sizing. I don't measure every case but If I happen to come across one like this I just check if it chambers still and carry on with life. If it happens to not chamber you'll have to measure them all and sort out the long ones then when your done screw your die down until it pushes them back to the same length and then re do anything that is long.Thats a great point.
