Mark, my experiences have been that the 10 gauge will throw better patterns then a 12 gauge regardless of load. They have stretched and twisted the 12 gauge's chamber to its maximum in an effort to keep up with the 10 gauge as they have with the 20 gauge in their efforts to keep up with the 16 gauge, thinking that a bigger chamber is all they need in order to get equal patterns from a smaller gauge. However, does the better pattern thrown by the 10 equal or exceed the huge price difference of shells between the 10 and 12 gauge or does the better pattern thrown equal or exceed the inconvenience of finding suitable shells when up in a remote area of Canada waterfowl hunting. No!! They’re neat for occasional hunting, though.
