I am using the "Lock Ring Eliminators" and the "Spline Drive Breech Lock Bushings." Both these combine the die lock ring with the breech lock bushing.
The discontinued Lock Ring Eliminators were machined from steel. They really only had one flaw: the pinch bolt was an internal hex-head (Allen) capscrew with a head that stuck out too far. The pinch bolt heads would interfere against adjacent lock rings in the Auto Breech Lock Pro's tight (turret) die holder top. If they had just swapped those capscrews out for some button-head internal hexalobular (Torx) screws, they would be golden. That's what I will do with mine. Instead, Lee replaced them with the "Spline Drive Breech Lock Bushings." They're machined from aluminum. I believe early versions came with a slot head capscrew (!). They had switched to a smaller diameter Allen bolt by the time mine were produced (I bought twelve). At first I thought they were good to go. I liked the four different colors for color coding although I could also use paint, colored sharpies, or colored electrical tape just as well.
Then I found that one of the bushings started to bind in the press head. That was really annoying. I had to order the spline drive wrench. The wrench is complete crap because it won't fit over the pinch bolt unless it's aligned just right which can sometimes be impossible with other dies in the way. With the breech lock bushings, I only ever use finger-tightness, so screwing around with a wrench to dislodged an aluminum bushing that's binding is very annoying. Not surprisingly, the bushing started to gall. Next it will probably jack up the press head. I'll probably be using anti-seize which will inevitably make a mess.
This is the kind of thing people who use Lee should already expect. If you want to be pampered, buy blue. If you don't mind working around someone else's shortcuts and poor choices, you'll figure something out.
