I just hit the range and must have picked up a gallon zip lock bag full of all 9mm if I had to guess. Haven't even sorted through it to confirm its all 9mm. Needless to say I didn't find any 10mm. Bought a glock 20 yesterday and a hornady die set. Cabelas had zero 10mm ammo when I bought my pistol. No one I town has 10mm in stock either. I have powder, primers, and projectiles on the way. Just need brass to get my newest safe queen up and running. I also have pewter besides the range pick up 9mm for trade. I'm looking for large pistol primer pocket 10mm brass. I'm short small pistol primers so n I want to save those for 9mm.
