I've been using the 41 Mag for years, myself and two Brother in Laws I use the Keith type SWC cast, 215 grs over a dose of Blue Dot and love it. I also load the Barnes 180 gr XPB and it is awesome, also with Blue Dot Ive taken a good many hogs and few deer with it, never a failure
Have been a 41 mag fan for years and have quite the herd, most of S&W breed.
My plinking load which has enough punch to hunt with is 215 grain cast over Universal Clays or Unique. Jacketed stuff sits over 2400. Haven't shot it in a while but even a wildcat the 41 GNR #2, a 445 super mag case necked down to 41 caliber, the Contender shown.
