You can do a search here and on other forums for that particular gun and find several threads and mentions.
Mine is .22 mag over .410. Haven't shot it tons but the shot seems right on and the .22 mag shoots about 4" high at 25 yds, IIRC. YMMV.
I like mine, it is wood stocked and has a case colored receiver. I don't know how much it weighs but it isn't really light. Nice little woods bumming gun though. Makes a good grouse gun, would work for squirrel too.
