I'm collapsing an occasional neck. It seems to balk at de-capping and then - with any more handle pressure - mashes down the neck.

I've adjusted the dies depth up and down many times - It's 2 turns down from shellholder contact right now.

Heavy chamfer on the inside - light on the outside of the neck.

Die is new. It's clean. It hasn't been altered in any way ... not polished.

Feels like the primers are tight as heck. They don't ease out ... they pop out. (once fired Federal - Frontier and PMC brass from factory loaded ammo)

What else I can do to prevent this?

RCBS Rock Chucker Supreme (beaucoup leverage)

.22-250

TIA

From the instructions in my Lee Collet set states: Screw the sizing die in until it contacts the shell holder, plus one turn more. Extra bullet grip can be obtained by screwing the die in an additional quarter-turn.

So.........from what I'm read you've screwed in the die too much. Back out again and start over.

Good luck

Instructions also say use two turns for presses that cam over the top.

I've had the die all over the place, all the way from no turns to 3 turns. Nothing's helping.

Polish & lube the collet assembly.
The dies I have all had a habit of not fully releasing the collar that contacts the shell holder and compress`s the collet on the case. This leaves it part way up in the die with a bit of compression on the collet which causes the case neck to not fully enter the die. When you raise the ram it chrushes the neck when the last couple .001" or so enters the die.
The case popping into the die fully may also be what you feel and have thought to be the primer popping out.

Thanks Joe. What should I use to polish it with?

I cleaned the factory preservative off the the collet and deprimeing pin unit and polished lightly with some 800 wet / dry paper. The dies I have had some fileings and dirt in the contact points of the collet and the sleeve. I lubed mine with shooters choice grease, but I believe any good oil or grease will do, although grease may collect dirt faster then oil, it hopefully won`t run.
You only need to lube the moveing parts lightly. too much oil and you could contaminate your cases inside if the oil runs down the decapping rod.

Sorry, I know I'll catch h*ll for this but: THROW THAT COLLET DIE AS FAR AS YOU CAN. I had about the same problem you did except that instead of crushing cases mine just pushed the POS aluminum cap up from its threads.

To solve the problem I bought RCBS like I should have in the first place.

Oh, one last thing all of you that think the Collet Dies are great send me the cost of shipping them to you and you can have my .250 Savage Die Set w/ the new aluminum cap that Lee sent me. Sean

I had the same problem, just open the jaws a little with something conical I used a set of needle point pliars and am getting great results.
