I'm in the same boat as Greg on this one, with a gun choked cyl/sk. I'm looking at jug choking or choke sleeving. It's not that you can't hit with cyl chokes, it's that crippling becomes an issue much past 25-30 yds. I had a chukar I thought was dead in my game vest show up on my work table the next morning, standing there waiting for me to dispatch the poor bird. That's not an experience I care to repeat.
