Ok....I'm new to reloading...I've bought some equipment and learning to take measurements and practing that.I am not reloading live ammo yet. So I'm trying to learn how to use the Hornady oal length guage, when I measure the chamber in my Savage 12 LRP, 6.5 CM, and compare that measurement to a factory loaded round using the the same bullet, my measurement is .077 shorter than the factory round , does that sound correct? I'm using the Hornady bullet comparator to take the measurements.
