I've been fire forming 22-250 brass and found a fair load in doing so but when I neck sized the once fired stuff I am building pressure. All cases are trimed, primer pockets and flash holes cleaned, necks are cleaned not turned. Any easy answers, as I have not had this happen before. Remington brass, Sierra 52 gr. bullets IMR 4064, and Win primers.
