I've heard of people putting an over shot card under a normal crimp to keep the buffer from leaking.

Is the Hartin crimp a partial crip ?

In a double barrel is there any chance of the load coming out in the unfired barrel...from the recoil of the other barrel after repeated firings...say in a hunting situation.

Jim I still have the pictures you sent me of your trimmers. I'll be glad to post them for you if you like.
