When you say "adjust your die down in the press more" how do you know if you have gone too far then?

valad:

Adjust your die down in increments, sizing a case as you go with each successive 1/8 turn of the die and insert the case into the chamber of the rifle (as I stated) and close the bolt. Still too tight when you close the bolt....adjust the die down a bit more , resize, and try in the chamber and close the bolt.

When you have it right, the bolt will close with only a slight resistance on the empty, re-sized case and that means you have now re-sized the neck/shoulder junction correctly without setting the shoulder back at all, or just the right amount, which is good.

(Setting the shoulder back too far can create an excessive head space issue which cam be measured by purchasing an RCBS Precision micrometer to avoid such a re-sizing error...more on that later).
