I've been debating about installing the Lock n Load hubs on my MEC and RCBS presses to use the bushings with the dies. It would be nice when changing out dies. The question I have is, has anyone noticed any substantial movement of the die when seating bullets? Are they consistent enough for seating and crimping? Bumping shoulders? I have a Lock n Load progressive press but never use it for my rifles. It came with the bushings and when I was checking them out it seems like there is some slop?
