Primer trouble or is it me

[atblis]

99% of primer problems come from not seating them fully. Make sure they are at least a hair below flush.

The other 1% is weak springs.

That's a lot of duds for 300 rounds.

The other possibility is that the gun is slightly out of battery (effectively causing light strikes). If your reloads won't chamber correctly...

I think I got it!!!
I loaded 150 rounds and shot them today without a failure. I checked my primer seating, adjusted the crimp a little, seated the bullets just a tad deeper and checked them against a factory round in the chamber on both of my 9mms to make sure they were seating properly.

I think I had a combination of things effecting my ammo. Thanks so much to everybody for your help.

Only one thing affected the primers not going off, and that was the seating depth. Glad to got it worked out.
