I was shooting handloads,I was using win small rifle primers, they are older primers, white box, not current manufactured primers. Went our earlier today and shot some rounds with no issues.
Winchester small rifle primers.
That's your problem.
Winchester primers have the softest cups. If I have a gun suffering from light primer strikes, I switch to Winchester primers.
On the other hand, you should not feed our AR's with Winchesters primers. I feed mine CCI, which have the hardest cup material. 400's for stick powders, 450's, or 41's for ball powders, and BR'4's when it that's what a particular combination likes.
