Over the last couple days I loaded about 2k 9mm for my handguns and ar15 with a new bullet I haven't used before. Left the die set set like its allways and figured id be just fine. Yesterday it dawned on me that I never tested them to see if they chambered. Come to find out they work in my ar but not my handguns. I can probably salvage them by running them all through a factory crimp die but I stare at that pile of ammo and sure hate to start running them all over again through the press to do that! Pretty stupid of me. You think after all these years id be smart enough to check them at the beginning. STUPID STUPID STUPID
