Write down the measurement.
If its a bolt gun you usually want to size your brass "0.002 shorter than the fired size.
For a gas gun you'll be looking to size it "0.003-" 0.005 shorter than fired size.
Test your sized brass to see if it chambers smoothly in your gun.
Is there a specific way to test to see if reloaded rounds chamber smoothly in a gas gun? I know it sounds like a stupid question, but what are we looking for when firing reloaded brass that is .003 shorter than the fired size?
