I was hunting rabbits, prairie dogs, and such with a friend. He just got a new Ruger Super Blackhawk in 44. He developed a blister and then wrapped his hand with tape. He didn't think that the gun rolled enough in his hand, so he added some baby powder to his tape job. I was sitting in the bed of the truck on a big gas tank with a 22.250. The deal was, I would take the long shots, and as he was driving, he got the short shots. To make a long story short, he reached up and took the gun off the dash, cocking it as he picked it up, slipped with the powder and touch off a full bore 44 through the windshield.
To say it rattled his brain, would be an understatement. Tape, good idea, baby powder, bad idea. Cocking the gun and having the finger on the trigger before having it pointed in the right direction, even worse.
