Hi bflobill69, I just joined this forum and know this is an old thread but wanted to share my experience. When I first started loading with my Lee Loadmaster I had several issues I had to learn how to overcome. I also experienced what you describe. What I found was that I had the seating plug set deeper than the crimp. I actually somehow set the seating depth first and then the crimp depth. What happened was I was crimping and then shoving the bullet deeper causing it to be loose. Also, what I found is different bullets (IE round nose, truncated cone) have different diameters above the case line. For my Taurus G2C I could not get the full bodied Lee 2 ogive round nose to work at all. I did come up with a workable load using the truncated cone at 1.060" COAL. I also was able to use the Lee TL356-124-2R bullet which has a smaller diameter nose than the body. It's been a few years since your post but I would be interested in what you found out.
