I agree. While there may be occasional bad lots of primers in some respects - I think how they are stored or used in conjunction with reloading practices create far more problems for shooters. Nothing to back that up - just seeing issues as to how folks do things that create problems leads me to believe this. In 50+ years, I have never had (that I recognized as) a truly bad batch of primers. Then again, maybe I did and wasn't aware it was the problem.....

I think it was CCI SR primers. On some I was reloading a few years ago I noticed the anvils were stained other brands were not. May have just been one batch. Also the priming compound was sqeezed up over the edges of the paper disc. The paper disc was also wrinkled.

Agree - I had several thousand of these primers and none besides this hand full had the issue. I'll blame me not decapping before wet tumbling and probably getting some chemical reaction during the air dry process or some dirt getting washed between the primer walls and the pocket causing this issue...

I only occasionally get my brass wet. It is almost always after necking up or down to a different caliber and/or when I get lube inside the case necks doing other operations on brass. I run them through a sonic cleaner to get all the contaminants, lube, etc. off Initially, I sometimes I did this with the primers intact. When the brass was dried and de-capped, it was noticeable that there was a bit more resistance in getting the primers to let loose. Not welded in, mind you - just noticeably more lodged in the brass. It surely is conceivable to me that they could really get stuck under the right conditions.
