I am fairly familiar with Lee molds. Most of mine are the 6 bangers. I own a few dual cavities, but most are roundball molds and see light use. I recently picked up a Bulgarian Makarov (fun little pistol!) and needed 95 gr pills. No 6 cavities to be found, so I went with the only option. Everything ran well for probably 500 or so casts. I noticed what appeared to be a ridge on the right side of the bullets after the spru was knocked off. I started paying attention, and just about every cast looked this way. It starts almost halfway across the bases, and probably is probably .040 higher than the rest of the base. Forget about accuracy! All the pins and screw appear tight. What is going on?
