Thread: ELD-M Getting Crushed when Seating

pretty sure there is something on Nathan Fosters site about this issue...as others have said they new super sleak shapes dont fit in older style seating stems.

Yeah mate get a vld seating stem and it will go away
I had this issue with my creedmoor with vlds and eldx vld stem fixed all issues

My basic Lee die has no issues with 180 ELDM

Eldx are longer again than eldm dunno if that makes a difference or the calibre but in 270 the tip was definitely hitting the top of the stem when seating

Can't edit my post but no issues with 162 ELD X or 180 ELD M for 7m Rem Mag

That is the internal diameter of the neck is 0.001" smaller than the measured projectile diameter. It's the same thing as 0.001" less than loaded

But if you didn't see the results on the first page, they shot pretty good!

A VLD stem may help but you arent bottoming out on the projectile tip anyways. But a VLD may give less of an angle onto the orgive.

@Kurt don't bother with the Hornady seating stem, it will do the same thing just not as bad. I had to go with the Redding VLD stem and seating die to not get any crimping. Got it from workshop innovations.

Yeah, I'll add one to my next brownells order when they'e back in stock (Wilson)

I have seen a ring around the top of vld projectiles when using my wilson seaters on brass with excessive neck tension but never dints like that. Are you having to really lean on the arbor press to get them to seat? did you chamfer the cases with a vld chamfering tool, are you lubing the case necks with graphite? Do you have a neck turning expander mandrel? if so I would run it through a few cases and try them. Is the brass brand new out of the bag or did you full length resize it for some reason first?

@Kurt

Try BRT in Aussie they are pretty good on Wilson gear

as above, it doesn't look like your problem is related to seating stems

I get it a bit with the 270 ELD X and ever so slight marks on the 6.5x55 but none on the 300's or 7mm Mag. Doesn't upset accuracy as far as I can see.

No excessive force required to seat, standard chamber, no lube, neck ID expanded to 0.001" less than projectile OD, brand new peterson brass, no full size just neck to reduce tension

Its odd...Could you borrow someone's dies to see if it remedies or repeats?
