Most of what I shoot is cheap, aluminum-cased CCI Blazer ammunition. My G26 eats it like it's candy - around 5000 rounds so far. But, I have had a couple issues. First, on two rounds back to back, I've had what appears to be blocked primer channels. The primers in these two rounds ruptured. I heard and felt a "pop" on each one, and treated them as squibs. As you can see, the primers were both partially blown out, and the gun was particularly filthy after that session. The second issue is recurring, and makes me wonder if I should shoot blazer at all. It seems that during feeding, the bullets are shoved deeper into the case. Note the bottom round: I've taken to pocketing any live, ejected rounds, refusing to fire them until they've been checked. I know lots of people shoot lots of Blazer without problems; should I be worried about the bullet seating too deep in the case?
