Was having trouble with my rifle throwing flyers. I was shooting 1/2 moa last year this spring I shot some groups and they had grown to 1 1/2 to two inches. the weather got so hot and humid I quit shooting for the summer and put it in the safe. I got it out and loaded some reworked brass and still 1 1/2 some times a flyer much worse. I tried seating the bullet out farther and seated in, same thing. Upped the charge, lowered the charge. Then I changed primers from Winchester to CCI. lightbulb Bingo that was it. Must have had a bad batch of primers. Never had that problem with the Winchester primers before. I have a bunch of them too.
