This thread reminds me of the first time I shot my blunderbuss.
I was being cautious since I had never shot a 4 bore and loaded only 65 gr FFG behind a small handfull of #1 buck.
One of my friends suggested 100gr FFG behind that same handful of buck...every time I reloaded. :yakyak:
After several shots, each with a slightly more powerful charge, and hearing, repeatedly, "put 100 grains in it", I charged that little gun with 100gr FFG and larger than normal handful of buck and handed it to my friend.
I stood behind him with arms outstretched, ready to catch the "buss" if he lost control of it.
He assured me that he knew what he was doing and turned to fire. That little gun bucked and Leo lost his grip on the forearm. recoil jerked Leo's firing arm out and up to the 2 O'clock position, to the rear of his shoulder, but he did hang on.
He looked at me with a shocked look and said, "that's enough, better go back to 65 gr." :surrender: :rotf: :rotf:
I normally shoot 80gr FFG using a ball of newspaper for an overpowder wad, a SMALL hanful of buck, and a small ball of newspaper over shot.
I can cover three police silhouettes placed side- by-side with buck at about 20 yards.
