For those that think screw in chokes are crazy, I wish the gun did not have them, but it came that way. It also has a 50 caliber barrel that goes with it. For hunting, it is the perfect one gun system. It is not PC, but it gets the job done.
The point was this, the full choke does not give the best long range patterns when using cardboard wad loads. It works well in modern loads with the shot cups. Lots of folks give up before they find the best load for their gun because they don't have a choke. They put up with so so patterns at longer ranges. This is my third black powder shotgun. Even my Navy 20 double would do good tight patterns at 30 yards. Of course, I spent a lot of time getting pounded by it to get it to shoot that well. Most of them will shoot a lot better than what is reported here on a regular basis, if you spend the time to work up the correct loads. It was not fun to pull the trigger on that Navy with heavy loads. The way it was stocked, it would swell the whole side of your face up after a few shots. I stuck with it until I found the right combo. It is not funny at all to shoot a heavy load out of the one I have now. At least it recoils straight back into your shoulder. I shot it a few shots a day for several weeks until I found the right load. The load work paid off this spring when a bird stopped to look at a little over 40 yards just a second too long!
When working on heavy recoiling shotgun loads, take some talcum powder with you to the range. Keep the cheekpiece powdered and you will take less of a beating.
