Die locking rings

[PaddyD]

This is no doubt going to sound like probably the dumbest question many of you have ever heard, but it has been bothering me since I started reloading almost 30 years ago. First let me say this happens on all my dies regardless of manufacturer. RCBS, Hornady it does not matter. I set my dies and the lock rings. No matter how tight I tighten those lock rings they come lose as soon as I remove the dies from the press. The RCBS using the set screw and the Hornady split ring clamping type it matters not. They just will not stay tight. Have I been doing something wrong? I thought about replacing the brass set screw in the RCBS dies with a steel one, but was worried about buggering up the die body threads. If any of you would please indulge me in how to avoid resetting the sizing die every single time I change it out I would be forever grateful.

Once you get the die set where you want it back it out of the press one turn,then tighten the set screw.

[GaryB]

Maybe try a little loctite.

[bigedp51]

Tighten the lock ring set screw until the threads start to smoke and then give the set screw one more full turn.

Or do what 243lpr said in post #2, but not Gorilla tight.

No, put a piece of #8 lead shot under the set screw. It will keep the set screw/ring tight while protecting the die threads from damage.

I have not been loading very long, well maybe a few years have already passed since I started. But, early on, when figuring out what to use, I read about many people using the Lyman lock rings on all their dies. So, that is what I have been doing. I have removed all the lock rings from my Lee, RCBS and Redding dies and use the Lyman ones. I have never had them come loose. Since they are a round style, I have to use a pair of locking pliers to install and remove them from the press. I wish they were multi sided so I could use an adjustable wrench, but I am happy with them overall.

Hornady Sure-Loc die rings have flats on them to use a "fits all".

Yeah, I thought about trying them in the past, but read a few negative reviews about the screws being weak. So, I just stayed with the Lyman.

Then get a bag of lee o-rings and put one under each of your sizing dies lock rings.

i use forster lock rings.

you can't tighten any of them with them screwed down tightly to the press. When you do it will hold that die tightly to the press kind of wedging it in there but it doesn't tighten the lock ring into the threads of the die. when you break it loose the ring turns on the die.

If you find your setting and carefully back both the lock ring and die out of the press, without changing their relationship, a quarter turn then you can actually tighten the lock ring into the threads of the die.

beware of lock rings that use a set screw that goes into the threads of the die. crossbolt lock rings are best and i feel the forster lock rings are the best of those.

Forgot about that trick.

Yep

I have found that with many of my dies I can reduce neck RO by using and o-ring under the nut. this allows minor adjustments to be made when I am getting it set up. An index mark with a Marker on the press face and the lock ring allow me to repeat the setting.

That's a great idea.

Thanks. That makes sense.

[Zero333]

I replaced the set crews with actual screws that can be tightened much harder and don't come loose...

Here is a bad pic, but you'll get the idea.

I have no idea what thread they are. I just found some at home that fit.

Possibly a dumber than dirt question-

When you are removing the die, is the locking ring "frozen" against the top of the press, and if so, do you use a wrench around the ring or the neck of the die to get it loose?

l if you tightened it with your hand you should be able to loosen it with your hand

if you turned the lock ring down tight to the top of the press and then tightened a crossbolt style lock ring you will probably have to loosen the allen screw to screw it out.
