The Syracuse Arms gun seen in the recent Eurasian Dove thread is a Grade 0 gun with 30" twist (marked "New Twist") barrels; on that particular day I was shooting Polywad Vintager 7/8" loads, but regularly use 1 and 1 1/8 ounce low-pressure hand loads. That gun is fun to shoot and very effective on doves (when I do my part!); so, when loaded to period pressures, I see no reason why such a gun should not be used for the purpose its maker originally intended.
