Thread: Resizing inconsistency - Am I missing something

I should probably be a bit clearer.

Fired cases are usually 1.766-1.768"
Zero clearance is 1.767"
I'm aiming for 1.765±0.001".
When sizing I usually get 0.004" of variance, depending on how I have the die set e.g 1.763-1.766 or 1.764-1.767.
Every now and then there will be cases which do strange things, but I've also changed lube recently.

However I haven't measured how much difference the case volume makes to velocity. It maybe inconsequential. I do know it affects bullet jump but In my case the change is irrelevant.
