I am planning to shoot my 41 Magnum Smith & Wesson Model 58 next year in IDPAs Stock Service Revolver Division. In the ancient days, when I could still see my feet, there was the hunting load and the police load. The police load is history now in my area so I am trying to reload to duplicate the 210 grain SWC to 900+- fps. It has been a challenge. Light loads make extraction difficult and the standard deviation makes accuracy not acceptable. Any one got any experience in working with this dinosaur?
