Oh My I just got the scare of my life. I think I will take all of these down and replace with known powder. Old powder as fertilizer
I don't think I am supposed to post the link but here is a copy and paste and I see info like this around
Problems Reported with Cal. 30/06, M2 Korean Ball (KA and PS) Problems with Cal .30/06, PS 75, M2 Korean BallOn 28 August 2004 at English Range, Fort Benning, Georgia, an incident occurred with the use of the Korean produced M2 Ball, Lot PS-2-158 in a Remington Manufactured US Rifle, M1903. After several successful firings with US Lake City produced M2 Ball through this weapon, a switch was made to the Korean Produced M2 Ball ammunition. When the second PS-75 round was fired, the case ruptured (split), causing hot gases and brass fragments to be thrown back into the face of the shooter. The shooter came a way with a bloody face that looked much worse than it actually was. Several brass fragments hit his face causing many tiny cuts. There were also some minor flash burns from the hot gasses. Fortunately this shooter was wearing safety lenses and received no fragments in his eyes. 23 nicks were counted in the lenses of his glasses caused by brass fragments.
For those among you who may be more inclined to worry about the Rifle than the shooter, be advised that the US M1903 Rifle came away also unscathed save for the first inch of the weapon's bolt having been instantly brass coated. This was easily wiped off. No mechanical problems were observed.
