Thread: My projectiles are being gouged upon seating...

Anybody had this issue? I'm seating flat base .277 interlocks into FL sized, chamfered and deburred cases with a Lee seating die. Am I putting too sharp of an edge on the case mouth or are my projectiles going into the seating die on the piss? Also I've noticed my over all cartridge length seams to vary with my loads. Could this simply be a variation in the lead tips from bullet to bullet? The orgives all seam to line up when observed on the loading block, which I'm guessing is the important bit. I was set on an OAL of 83.35mm for now, but I've had variations go from 82.9-83.42mm. Maybe I'm just being too anal.
