Heck, no, it's not an ideal clays gun.
Heck yes, you should take it to the range.
First, the practice will aid your handling skills no end,and instill confidence.
Second, you might be surprised, and surprising, at how good you do with it. My clays gun, for casual shooting, is an 870 I kitchen tabled from a receiver from the Md Pen and a 21" bbl with Colonial tubes installed.I do OK with it, and few have laughed.
And face it, how many folks are going to mock someone standing there holding a riot gun(G)?
Coupla suggestions....
First, get tubes installed, I'd get an IC or a Skeet II tube.
Then, get the forcing cone lengthened. This reduces pellet distortion and keeps them in the pattern. Lowers recoil a trifle too.
Next,pattern your weapon until you know where it hits, and adjust the stock if needed to place the pattern dead on or a little high.
Good luck and have fun, be safe....
