Idk where it came from lol when I was cleaning out the striker channel, at the deepest part of it there is a fat pin, about a quarter of an inch wide, that holds the I guess its the ejector, in. I was pressing it in with my finger, because doing so let me get my qtip deeper into the channel, and after I pressed it in a few times, it literally was like popping a mega gross zit or something, this yellowy brown crud came out. I don't think that caused any problems but in the channel was a lot of junk shavings and just crud which I thought may have cause them . I have been doing research for the past few hours and I'd put money on it's my primers not being seated all the way. I took 100 of my reloads and sat them all up straight and there were three that had an extremely slight wobble to them. It was very slight. But I marked them with a marker and will see if they cause issues. It may have been wishful thinking but like I said i d bet money on it. My wife loves reloading for some reason (I know i m blessed), I think she thinks she can do it faster than me and will take over whenever she catches me doing it. I noticed that I'll shoot 150 rounds without issue. And in the next boxx I might get 5 light strikes in 25 rounds. Not tryna Blame her lol but I think this may be the Case lmao. I'm gonna pick up some factory this week and will get back to the forum
