I have been using lock rings from a smaller company called McJ Tools. They make a few other things I like as well. They lock down super tight and I've never had a problem with them. These are on all of my dies. I know the other brands mentioned work well too but I'm sticking with these.

Hornady make a good lock ring. It will stay put if secured properly.

Man, I guess I have been lucky. I have never had a die lock ring move once set. Either the RCBS/Redding type set screw or the Forster/Whidden/Hornady type clamp screw.

Put a drop of red lock tight on your set ring. One tube will do about 400 die sets, and will cost about $.03 per die.

I have to use the set-screw style for my press, no choice, but I drop a #6 birdshot down in there. Those babies never move again until I want them to and the set screw never mangles the threads again.

I use Forster, but I also mark the die and ring with a fine tip sharpie. That way you have a quick visual reference on whether your die setup has changed.

I think the cross-bolt rings are far superior to the more conventional rings. However, almost all of my dies are Redding and they have conventional rings. None of these rings have ever failed or loosened on their own. So ................ if it ain't broke, don't fix it.

I've used these from Lee. I like the "O" ring. It fits snug.

Good point, I have one of those on the factory crimp die... Okay, I must admit two things:

1. one die doesn't have the Hornady ring.

2. it works also!
