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.
I do LOVE my S&W Model 57 - 8 3/8" 41 Rem Mag with a 2-7x20 Vortex scope.
XTP and Fusion 210gr have always worked great. I now have several boxes of Hornady LeverRevolution 190gr, but have not harvested anything with them.
My furthest shot was 79 yards on a young spike who ran about 45 yards to expire.
That's a big gun and a heck of a tool.
One of the things I love about my 41 is that is a 6 and a 1/2" and serves as a great hip gun.
I have several long barrels (rifle cals) for my contender and sometimes carry them both at the same time... Sometimes a rifle and the hip gun, sometimes a rimfire and the hip gun. Sometimes the Contender and a rimfire.
I love versaticity (Ben Rogers Lee).
