Just bought a bunch of CCI blazers in .357, and these things are almost impossible to extract from the cylinder when fired. I shot 1 cylinder, then had to put the extractor rod against the seat, and lean on the gun to force them out. Ok, I thought, aluminum cases. I shot the rest off one at a time, so I could still manually eject the case. But when fired, I also see a blast of fire come out the sides of the gun, from the cylinder gap. Is this normal? I've never experienced it with any other ammo.
