cmat, I'd encourage you to get some of the type of measuring tools mentioned above. Then just for a little learning experience back your die out from where you have it set for a good fit to your chamber a 1/4 turn. then with a piece of fired brass size it and measure every which way you can think of. Take notes and repeat moving in small steps toward your initial or "good fit" setting. Measuring at each step. by doing this you'll find out what your brass is doing in the sizing process. Have fun and always be safe! Oh by the way welcome, you can learn a lot here. I know I have.
