Shouldnt cause anyIf I have a 3.6" magazine feeding a 3.35" loaded round, what kind of negative issues can that cause?
What does that matter?If the magazine is loaded with care it shouldn't cause problems, unless some are loaded too far forward.
Too far forward, depending on the bullet, a sharp pointed bullet like a Berger lbVLD may get pushed against the front of the mag and jam as it cannot slide forward into battery.What does that matter?
