If you've got a tight barrel or two, always good to pattern and see just HOW tight. My former backyard patterning setup limited me to 35 yards. My #2 Army and Navy, referred to earlier, came with chokes of .005/.040. I patterned the left barrel at 35 yards with my pet 1 1/8 oz low pressure reload: 90%+! Since I wasn't going to use that gun for turkeys, that's when I decided to open it to .025. Still tighter than I had in #1, but as much choke as I figured I'd ever need on pheasants. Frankly, probably more than enough.
