Partial Sizing of Bottle-Neck Cases?

[Adam Helmer]

dovehunter,

I partial resize all my bottleneck cases even for the three Match M14s I have loaded for. Rather than use a matchbook, I suggest you use the Individual rifle to "tell" you when you have sized the case enough. I relaod for specific arms and have the rifle at the bench when I reload for it. I back off the resizing die a half turn, run a lubed case into the die and then try it in the rifle. If NO GO, I turn the sizing die down a bit and try that case again. Once I get a slight crunch fit, I lock the die and record the setting for future reference. I put a reloading data sheet in the box of reloads indicating the specific rifle the loads are for. Backing off the sizing die to size to the case shoulder is critical in my 7mm RM. Failure to do so gives case seperations quickly.

Recently a guy came by with his .300 Weatherby dies and components to load for his Remington 700 rifle. I asked him where the rifle was and he said at home. I told him he had to go get the rifle so we could load for it. He went and got his rifle and then we reloaded.
