I had sticking problems and found the hull was slightly too long and was jamming in the forcing cone. Shortened them about .025 and problem solved. Also, the raised diamond on the base of the hull had enough additional thickness that on a couple of guns--one a Parker and the other a early English gun--they wouldn't close. Lathe turned the diamond off and they now work perfectly. Oh, I also reduced the diameter of the rims .015, they were a little too wide in my Brit gun.
These hulls are very well built and I recommend them. They are lathe turned and have quite thin walls so be sure to use 9 gauge wads for loading. Circle Fly Wads has everything you'll need.
