That is interesting. Why don't you like the lock rings? I love the fact I can swap out my dies so easily with very minimal re adjustment. Why do you find them annoying out of curiosity?
I load single stage so for each step you take out the die and put the next one in. With real lock rings, you set the die up one time, lock the ring, and every time thereafter when you put it in the press, it is set up ready to go. With the rubber O-ring locks, they always
are out of adjustment when you put them back in. I just got some lock rings from Hornady to replace the locks on the Lee dies.
I have three sets of pistol dies from Lee. They work just fine. They are a little less expensive than the other brands and they were available the day I wanted some. The availability issue is why I ended up with the Lee dies in the first place. I would have spent the few $ more if another brand had been available. Ya, I know, I could have ordered and waited for shipping, but I gotta have it NOW!
The Lee die set has a Powder Through expander die and the sizer has the decapping pin, where some of the other brands have a decapping rod in combo with the expander, and the sizer just sizes. This powder through die may be great if using a turret press. For single stage it really makes no difference.
I don't have any Lee rifle dies, so can't comment there, except to say bottleneck rifle die sets usually only have two dies. The decapper doubles as the inside expander tool and is mounted on the sizer. Belling is not an option. The other die is the seating die. Some have crimp rings in them.
One plus with Lee dies, the shell holder is often included.
