Whats everyone using? I'm currently using the lee lock stud with a pair of vice grips around the shell holder for quick tighten and loosening. It gets the job done, the length is very consistent, and it actually works very well, but it seems like the shell alignment isn't consistent and sometimes the shell tips from parallel. The quill in the tailstock is a fairly loose fit, and I let it float so it should be somewhat self aligning. I'm just thinking something a little more consistent in alignment would be better. I've devised a couple ideas to implement a collet type system like is seen on the forster trimmers, but those never really turned me on for the fact that the more the collet is tightened, the deeper it is drawn into the housing, and further away from the cutter head, and since the case head sits on a step inside the collet a variation in case head diameter will directly cause a variation in overall length.
