Lancaster,

Again, great data and thanks for sharing. I now see what you meant by a "conical" shell. It appears that is what I have and I guess I will have to live with the possibility of splitting 16 gauge polywad or whatever I have on hand.

Wonder if anyone in Europe is manufacturing the "conical" ammo?

Thanks again for your posts and sharing of expertise here. I really do like this arm quite a bit and cant wait to take it to the fields of the Dakotas next year.
