Today I made up a couple of dummy rounds to check. I'm using the Lee 452-230-TC. To get the dummy to chamber I ended up sweating it to an over all length of 1.245. Is it normal to have to seat this boolit deeper like this? Also when feeding from the magazine I can see a slight mark from the feed ramp. I cant really feel any distortion more like a polished spot is this normal or should I harden my alloy ( 50/50 rotometals lyman #2/ pure) or am I being overly cautious ? Thanks for the help gentlemen
