Helping a new guy load 9mm and found his handgun has a very tight chamber. My size die, Hornady carbide, doesn’t get the base small enough on all cases for easy chambering. We sized and checked for fit enough cases to get 50 that were OK. Seems some of my range pickups have a small bulge, maybe .001-.002, towards the base. This is far enough down to keep my sizer from touching it.
Made a push thru die today. Wanted .389 as a final size because that is what the “good cases” measure. Other cases measure .391+.
Forgot about spring back so the sized cases go .390. Handgun is now 5 hours away so I can’t check to see if it works. Easy enough to make another slightly smaller.
A little case lube and they go thru smooth as can be.
