Hi, yesterday I shot a box of remington UMC (cheap stuff) with my 9mm, as well as 3 boxes of WWB, when I got home I noticed all these yellow powder particles EVERYWHERE inside my P226 and between the slide and the frame (WTF). I have seen it one time on an other forum when someone got a rifle cartridge full of this yellow crap, and he was told he didn't reload it properly and the powder got contaminated. But this is factory stuff I shot, it's not supposed to have any funky powder.
Did anyone encounter this?
