At the shoot yesterday (thanks Ed) I finally got to shoot some of my PDX1 Defender 12 gauge shells (the ones with the 1oz slug and three 00 pellets). Results against a pumpkin were pretty spectacular, but more importantly they cycled my KS-12 (US built Saiga 12) just fine. They can be temperamental with some loads. Sorry about the lack of pics, I wasn't thinking about it at the time, but wanted to pass on the results.
