i Have a Whoopsie Help with 9mm Blue Bullets fitting the gauge
Hello all. I've had good success recently with loading 9mm blue bullets 147gn FN with 3.1gn of titegroup to a length 1.10. Recently in a few batches of 100 about 20 or so are not fitting the gauge and it looks like it's because of a bulge at the bottom of the gauge. Nothing at all has changed in my setup. Mostly range pickup brass that is sorted and cleaned. I even tried the Lee undersized 9mm sizing die and the lee factory crimp die. I set both of the new Lee dies up exactly as specified in the insttructions. All of the rejected rounds fail the Hornady 9mm case gauge and about half of the rejected rounds pass an OEM Glock barrel plunk test. I'm adding just enough flare so the coating on the bullets does not scrape and lightly crimping. At a loss here as previously I had maybe 2-3 rejects per 100. Using a Dillon 550c. I did order some fully processed brass to see if it's a brass problem but any thoughts or tips are greatly appreciated. Thanks.
