I have been using a standard Redding and/or a Lee seating die to seat 142 gr. SMK's for a long time and thought I was doing just fine. I rolled a loaded cartridge across the bench and saw that it was obviously not straight. I took both of the seating dies apart and could see that the seating stem was not deep enough to allow the bullet to move far enough in to contact the bullet on the ogive. The bullet was hitting the top of the seating stem cavity and this was allowing for some serious misalignment some of the time. Problem can be solved with a replacement Micrometer Seating Stem for standard die from Redding or buying a Bench Rest Seating die from Forester. Thought this might be of interest to some of you. There are probably other ways to solve this problem and I would like to hear from any of you that have a different solution.
