UPDATE-Dents in shoulders

[snert]

take the die apart, blast it with carb cleaner, scrub it with a brass brush (shotgun) then blast it again. When done, hit the outside with some rem-oil. Use some imperial on your next brass, just enough so that when you rub your finger to thumb it slides. Dont get it on your necks. Might try dry lube on your necks (inside)

Or instead of imperial, use Hornady One Stuck and be careful...if at first the case is resistant, stop, back it out, spray it again, let it dry, try again.

When you clean a die like this, you need to season it with lube...go slow, little bit at atime. The inside will be dry dry dry when cleaned with carb or brake cleaner. go slow at first, like its her first time

As others said to much lube and it builds up in the die. Clean the die, and don't spray the cases, apply the one shot by rolling or wiping it on the case just below the shoulder. Use your finger or spray it on a paper towel.

Also, Redding Dies used to not have a vent hole. Just saying.

If you over anneal and then use a die that doesn’t have a vent hole, you can make a dent like those. The “too much lube” dents l have seen don’t look like those.

Yep, dents look too consistent to be over-lubed.
but I’ve never had shoulder dents, I use Imperial wax

Forgot to say , make sure you take your die apart and clean it!

Check that the vent hole in the die is open as well when cleaning the die.

Let us know what the problem was.

As stated many times , maybe over annealed combined with to much lube and maybe a clogged vent hole.... Clean your die and pre lube it afterwards.... Load them up and shoot again to remove the dents....

Quick update -- cleaned die, it's a few years old no vent hole found. Loaded and fired 20 pieces of the brass with dents (dents removed). Went back to old way of doing brass prep! No anneal, back to full length sizing die with sizing ball installed, Hornady unique sizing wax on a lube pad, small dab in the neck! No dents in shoulder!!! Not sure what caused the dents because annealing, oneshot ,and sizing mandrels were all new to me. Gave the one shot to a buddy, sold him the annealer and I have a Sinclair mandrel and 3 sizing Mandrels for sale! Right or wrong, I'm going back to what I was doing!!
Thanks Bill

So there is no vent hole in your FL die?

No there is not. I have 3 sets of Redding dies with no vent holes.
Thanks Bill

The die needed cleaning. Glad your fixed.

I would consider continuing annealing. Inconsistent shoulder dents are lube, consitent shoulder dents are a die that needs cleaning. Thanks for the follow-up report.

Those are lube dents, but. . .

All that time and trouble in brass, equipment, etc, and you're using OneShot? The first piece of stuck brass will cost you more than a lifetime supply of the lube you should be using.

Buy a tin of Redding or Creedmoor wax lube.
