In the early 80's I had two Redhawks, a 7.5" with a 4x12 pistol scope, and a 5.5" with just the iron sights. Both shot ~1-1.5" groups at 25-75 yards off a rest, no problems. My loads were a 240 cast "Keith" SWC that my gunsmith made, over 18.5 gr of 2400. Plenty of punch.

One day at the outdoor club I shot at, two "yayhoos" showed up with a new 7.5" Redhawk and their own loads. Each round had a orange ball of flame about 3 feet in diameter, and turned people's heads at the skeet range a quarter mile away. (No fun sitting 30' away at the other end of the bench. Felt like an earthquake). They sat it down, opened the cylinder, and tried to eject the cases - big fail. I got a ball peen out of my trunk, and they destroyed a cleaning rod pounding the cases out. I asked "What did you load?" Answer was 24 gr of 2400... and a 240 gr JHP...

Ummm - ok.
