Larry, I got a surprise when I walked up to a sheet of white cardboard I used for patterning after opening my 16ga Sauer from F/F to C/IC a couple months ago. It appeared from six- or eight feet that I had missed the board, set up on a tree in the snow. Dear god, only on looking more closely did I see tiny pellet holes and remembered that I had picked up a couple No. 9 lead reloads. Looking at the back was the best pattern I had ever seen, perfect, and so was the IC barrel's.
