Thought I would post some of my patterning tests. Ive been playing with different shells out of my Browning silver and Jellyhead .670 choke. All of these were tested at 50 yards. I did notice that the heavi shot penetrated the 3/4 plywood instead of just burying up in it like the lead Federal flight control shells. ;)All loads were heavishot loads but the Federals. 1st-NITRO H510C 23 HEAD 56 CIRCLE 129 PAPER
