Reloader7Rm and cra1948, I think I'm ditching the idea of using these shot shells in my SxS in spite of the obvious superior patterning relative to more traditional lead loads and the lack of any warnings. It's just not worth worrying about a bulged barrel or a sprung rib.
Interestingly, with the first round I fired, I saw an oblong 3" hole appear in the target at thirty yards. The wad never slowed up and pulled free. It acted like a very long slug though obviously was tumbling.
These things are 12ga-like in payload and velocity--a great load in a 20 pump or autoloader.
