I don't know about being a cannon load, any load out of a 10 ga seems to be a cannon load, but I thought you might want the best load for your Browning and Rhino, I have shot many different chokes and loads and the Rhino with Nitro beats them all by a long shot. I don't like shooting over 40 yards either but if I get one hung up at 50 I feel very comfortable with taking the shot.
