Recently at the range I encountered a problem with my PPK/S 22lr using CCI Blazer 22lr ammo. I was participating in a 30 round pistol shoot and was using my PPK/S and I loaded up a magazine with 6 rounds of the CCI Blazer ammo. I proceeded to start shooting and after the first shot went off, but I could not shoot the next round because the slide did not come back far enough to eject the empty shell casing. I dropped the magazine, cleared the chamber and reinserted the magazine, that round fired and again the slide did not come back far enough to extract the empty cartridge. I left the range, went home and picked up the following AMMO brands to see if I could duplicate the problem. Boy was I surprised when I took the following Ammo Brands, the CCI Blazer, CCI Mini Mag, CCI Standard Velocity, Aquila Super Extra HV, Geco Rifle LR, Norma Tac 22, to a local indoor shooting range. Every brand of ammo except the CCI Std Vel duplicated the problem originally encountered with the CCI Blazer 22lr ammo. Has anyone else experienced the same problem I had over the weekend?
