Eldx VS seating die - damage

[Mumzergadol]

Matchmaster seating die is destroying every 3rd or 4th 143eldx.

New lapua 65prc brass. Run over expander mandrel (262) for uniformity.

Load isn't compressed and I'm getting what appears to be actual extrusion of the bullet into the stem. I know the vlds shape are prone to scoring with standard stems, but can seem to find a vld Stem for this die.

Has anyone seen anything like this before??? How did you solve it?

Being new brass, the necks are probably squeaky clean. Did you lube the inside neck with dry lube? That may help it slide in with less force preventing that issue.

That's a good call out I didn't try. The mandrel has dry lube on it but maybe I'll try putting a squirt of one shot into the box of bullets

That's because, as far as I can tell, they don't fucking make one....they don't even seem to sell replacement stems separately that could ever find.

You can contact then and send them a bullet and your die and they will custom fit one to the other for $$....change VLD bullets, your guess is as good as mine.

Personally, I'd use a different seating die.....I use Redding Comp Seater with VLD stem (and yes, Redding makes VLD stems, sells stems separately, and are easy to change out).

Aside from lubing as suggested above, did you chamfer the inside of the necks?

And after running your .262" mandrel into the necks for .264" bullets, did you measure the resulting I.D.? Spring back, right?

Cheers
