Anybody have advice or experience with sizing 223 brass into 17-223? I just received my VERY EXPENSIVErcbs dies for forming 17-223 ackley from 223 brass. Being trying to size brass, looks good, but won't chamber (bolt won't close). The dies were made from a chamber cast and the rcbs tech had a chamber reamer in the same caliber to check headspace, so I don't think the dies are off, but what's outta whack?
The rifle is a Sako L461 that was barrelled by Ackley and has been fired (I assume) as it's 25 plus years old, with a nice Lyman scope.
What am I doing wrong?
