Many years ago, Tony Montemurra at the Sportsman's Exchange in Oxnard (of Oxnard fame) had a worker named George. George loved the thought of shooting a double rifle but had never tried one. One day at the range, he talked the owner of a 577 Nitro into shooting his double. George touched off the front trigger and the gun roared....and raised in the air...and came off his shoulder....and Georges finger brushed into the rear trigger....and...the result resembled hammering a wooden stake into the ground. Once we observed nothing was broken (George being a good buddy, we checked the gun first), we started laughing. We haven't stopped laughing after about 30 years but I don't know if George shares our opinion yet.
