has anybody ever chronographed the 41 mag Remington police load from a M-58 or 4 inch M-57? I think it was rated at 950 fps but I don't remember if they were using the "vented" barrel. I use 7.5 grains of Unique with a 215 grain swc and that is an average of 1,000 fps out of a 4 inch M-57. I think that is a little high for the police load.
