Thanks for the help and ideas. HS101-All springs are stock in my 34 G-manBart-I individualy inspect each round after loading and I am 99% sure the primers are seated correctly. My definition of "seated" is slightly below the case bottom. I am using mix of brass so it is concievable that the primer is below the base but not "fully seated". I use a Dillion 650 and these primers are "easier" to seat than others I have used.

Last year I purchased 10K of PMC heavy metal free small pistol primers. I just got into them when reloading my latest batch of 9mm. I have only loaded alittle over 1K and was out running some drills with my G34 when I got 4 light primer hits out of 300+ rounds fired. I reloaded the unfired rounds into a magizine and they all fired the 2nd time. I have never had a light primer strike with any glock much less this 34 (10K + rounds through the gun). I cleaned the gun (It was dirty, using Bullseye powder on the reloads) but I am hesitant to keep loading using these primers. Has anyone had a simular experience? Are these hard primers?
