I actually have a bit of a sporting clays addiction, and yes, I do it the "clean" way, starting with the gun at port arms rather than half-mounted the way most ranges allow you to do it these days...
So I'll likely keep on shooting clays right up til I go to Africa in any case. It's good to know that all my time wasted on sporting clays courses hasn't been a total waste!
... I appreciate all the input you guys have given on this thread. I'm feeling very comfortable with my 375 choice at this point.
