FL sizing ?

[RichinVA]

First forget the unfired case as the measurements have nothing to do with your rifle. If you have a fired case from your rifle and it measures 2.042 then adjust the die to set the case back to 2.040. These numbers are right in line with the 2 30-06's I load for.

You also have to remember that the gauge you are using may not be exact as it is a mass produced piece of aluminum but for what we do with it it will work just fine. Your numbers might not be the same as other peoples numbers due to the gauge but your numbers are all that matter.

As good an explanation as I have seen anywhere, ever. And in less than 5,000 words.......

Succinct and precise.
