Certainly sounds like it's an incompatibility between the Dlask chamber and the Blazer ammo. I saw a shredded case just like that recently from a guy's Ruger MKIII - he had done a faulty trigger job and the gun fired full automatic. The last cartridge looked like the one in the picture (on the left) and also threw out shrapnel. I think the bolt was not in battery when the last round ignited. If the round is not fully seated in the Dlask chamber it would likely have similar results.
I have fired thousands of rounds of CCI Blazer in various handguns and rifles with no problems whatsoever. It's pretty accurate for HV and so far I've had only a single misfire. So I wouldn't blame the ammunition itself. It's more of a mismatch between the ammo and that particular gun.
