Interesting article in the latest handloader magazine. At some point in time the Brits had a 45 caliber manstopper bullet for their 455 webley revolvers. Big hollow point bullet. Well Bob Haley in texas came up with one for the 38 special same as it's bigger brother but at 140 grains. !40 grains would easily get to 800 fps without straining anything. Good article. And get the single shot mag from wolf publishing while you are at it. Good read. Frank
