Factory ammo, popping/flat primers

[Hawkeye7br]

Wow!!! 2800-2900 fps with a 180 grainer, thats sounds like an overcharged batch. Check some reloding manuals, Hodgon website has max loads doing 2600-2700fps ranges with only one load hitting 2800 fps. and that is out of a 24 in barrel, I dont know your barrel length, but I bet it is 22 inches. I would not continue shooting these. Blown primer ,Flat primer = HIGH PRESSURE

Yeah, what he said. The other poster who recommended pulling the bullets and dumping the powder to use less of it.....good idea. No need to overpressure the case and ruin it for future use.
