A while back I was telling a few here that I had a few CCI LRP not working in some 45-70 loads I worked up. I was very frustrated as I had 60 more that I loaded and was afraid they wouldn’t go boom.
I finally got around to pulling a few of the cases that ftf. I was mystified because the primer was clearly decomposed, and the powder was clumped up and sticky.
I let the cases sit open for a few days due to my work load. When I came back to them, the powder was flaky, as it was supposed to be. I pulled another and it was clumpy but it dried within a few hours. I initially thought resizing lube had contaminated the powder and primer. After seeing the powder go from clumping to loose and flaky, I think I still had water from wet tumbling in them.
I shook the rest and could hear the powder shifting so I think they’re good. I have since added time in the oven at 170 degrees to all my brass processing if I need it soon. Lesson learned.
