Here's a technique which I've used to adjust a sizing die to size the minimum amount. This method seems crude, but it seems to work just fine. If possible, I get some once fired brass which has been fired in a chamber which is larger than the chamber I'm working with. This brass will not easily chamber in the rifle and I don't force it. Remove the decapping-expander assembly from your die. With the shell holder at its highest point turn the sizing die down until it contacts the shellholder, then back it away one complete turn. Size your case in the die and try it in the rifle. If the bolt will not close or closes hard, turn the die down 1/8 of a turn and size the case again. Continue this process until you obtain the feel (resistance to closing) on the bolt that you want. You may have to turn in less than 1/8 turn increments to fine tune the die. Now tighten the lock ring in place. This adjusts the headspace of the die to your rifle. You should note that this method has worked well for me in bolt action rifles. I would not care to use the same technique when loading for semi-autos. Each time brass is loaded, it gets work hardened a bit more. As the brass hardens, it will be less malleable. When your sizing die, sizes it down, the brass will tend to resist staying sized. In other words, the harder the brass gets, the more it will tend to spring back to where it was prior to being sized. It is not hard to imagine that after several reloadings, your semi-auto could cease to digest these reloads. |

I just had an issue with too soft a brass, I guess there is a happy median. |

You may have to anneal it when it gets soft. Basically you would heat it until you felt the heat while holding at bottom and then drop it into a bucket of water. |

This particular brass has only been shot once, I read it hardens as you shoot it so I will give it one more round to see what happens. But I had wondered why some others looked burnt on the top, thank you. |

Brass that has been annealed will have the burnt appearance around the neck. |
