>>1291244>shotshellMake sure you use brass cartridge ones. I still have a piece of shrapnel in my leg from a .22lr shotshell that had a cartridge made of some grey-silver metal (pic). The rim, where the hammer hits, exploded. The shot shell was intact, but the explosion went out the rim, and down into the magazine. There was a nice little explosion when the entire magazine of exploding shotshells were blown into my thighs.
