I corrected a mistake assembling 40-182 TC Lee PC testloads today. Originally, I resized a certain quantity of cast bullets and used some resized and flared casings. I ran out and without thinking seated bullets into cases where the bullets just barely fit. This worked for jacketed bullets before. But sometimes, the paint would sheer off the edge of the case. I thought about leading from loads I may not notice with exposed lead. So today, I culled all the brass that didn't show a clear roll crimp and assembled replacement test loads with flared casings and sized bullets. I pulled the other bullets to inspect them. Here are the best examples. The top row is what I pulled from the original testloads that I culled. The second row are dummy loads I made to replicate and confirm my theory. The left column is a PC bullet seated into a flared case (the mark on the top is from the kinetic puller). The center column shows bullets seated into a case mouth that wasn't flared but the bullet could seem to fit into the case mouth. And the right column is a bullet seated in a flared case and then crimped, then seating depth was increased to acquire a specific COL. From now on, I'm seating the bullet first and crimping the case so the flare is flat but not cinched into the lead bullet or separating the seating process and the crimping process.
