Jefe,
i wish you'd had some factory ammo to try.
from your description it does sound like excessive headspace.
but new brass might be even smaller than minimum, i'm not sure.
a go gauge and a no go gauge would be the best test of headspace. i don't have a set for the 6.5 Grendel.
i'm hesitant to say overlong chamber though. i suppose one could slip through QC in any company. i more suspect your lot of brass was made to a really minimal print.
let us know what Brownells' has to say.
and yes, your die set sounds suspicious. something funny there too. with industry mfgr's running full tilt boogie and still not keeping up with demand, it's possible a mixup on dies i suppose. someone got in too big a hurry perhaps?
let us know what Redding has to say too.
