If you are using Lee dies with the o-ring lock rings, you may find the breech lock more user friendly. You set the die and jam the lock ring against the breech lock bushing. The die will then maintain its setting.
Another option is to buy replacement lock rings with a clamping feature, either a split ring or a set screw.
A third option is to drill and tap the Lee rings for a set screw. Place a lead shot under the set crew to protect the threads.
A fourth option is to install two Lee lock rings on the die and jam them together in position. Trouble here is the die may not be long enough to hold two lock rings and you still need to buy more lock rings. I have done this on occasions to save money when I replaced the lock ring on my Lee dies and had copious quantities of Lee lock rings in inventory.
A fifth option is to get a Lee turret press and a turret for each cartridge that you pan to load. The lock ring can be jammed against the turret. Change turrets to change cartridges. Get the cast iron turret press if you get a Lee turret press.
Regardless what Lee says about removing and reinstalling their lock rings without upsetting the adjustment, it just does not work reliably. Not if, but when you upset the adjustment it will be at those times you will forget to check the die setting and process a bunch of brass improperly. The lock ring needs to be locked in place, not held by an o-ring.
It is interesting that Lee has introduced a breech lock bushing with a split ring attached for locking the die in position.
My opinion and my experience using Lee dies. Others will most certainly disagree.
