Walther PPK/S in .22 LR Took 4 different boxes of ammo to see what she liked best. All went well till I tried a box of Hansen Cartridge Company ammo. First round fired and I gor a face and EYE full of blowback powder. Seems the case head blew,and I was amazed at the amount of 'stuff' that came back at me. If not for my safety glasses I know I would have needed a hospital visit. And possible permanent eye damage was a real item.
