I've noticed that I'm having some FTF's with handloads that normally would have gone off with no problem in my traded-away Norinco's. The primers show strikes, but they haven't gone off. I'm wondering if the M&P is sensitive to harder (read CCI) primers, as opposed to Winchester or Federal?

Well...CCI primers are the least sensitive primers available, I think there might be some striker issues also, maybe someone who is better informed on that issue will chime in.

I had a few light primer strikes very early on, but nothing since then.

How deep are you pressing the primers into the cases?

I had some earliy on but got the updated striker, and went to federal after problems with CCI.



I'm now back to CCI with no problems.

I've been using winchester WSP with no issues, probably 500 through my 9c.

I had problems with CCI's in my XL650 not fully seating. I switched to WIN and had 0 problems.
