I ve been reloading 9mm for a few months now, I was checking on my dies before loading to make sure nothing had loosen up from last session and I noticed 9x21 written on my resizing die. I purchased this Hornady set from a Calbelas that had just opened in West HarT, CT a while ago. the 3 die set was on sale and I thought oh I'll reload 9mm some day. I still think the outer packaging stated it would load all the 9mm versions. I have the hard box but it only states 9x21. Of just recent, I started on my "found on the ground" federal 9mm cases, I load by head stamp. this is the first time its happen to me but 2 rounds didn't hold the tip when chambering and the tip was pushed in the case. 1 round I couldnt push in by hand and thought maybe it had just got by my checks however the 2nd round I pushed against my bench and it went right in without trouble. before anyone says it I already have order an undersized 9mm re-sizing Lee die from EGW, but My question is this shouldn't 9x21 set be able to load 9x19 without issues?
