I put Brileys in the single barrel of my trap gun. A situation where it really showed the advantage: normally I was shooting Arizona and occasionally Florida. Then I took a trip around Colorado, it made a heck of a difference being able to open up the choke in Leadville for the handicap. The full choke I had in the gun shot like a rifle at that altitude.
I have also put Brileys in a model 23 that worked out great.
