When you start working loads dont forget 2400. Been shooting .41s almost exclusively since 1989. Think Ive tried just about every thing out there that is even remotely suggested for use in the .41. I keep coming back to 2400. I always found that 2400 produces a different kind of recoil than the other powders I use. From the summer of 2000 until October 2001 while I couldnt shoot anything I did lots of ballistic research. One of the most interesting things I found was work that was done on the power curve of various powders during their burn. 99.9% ignite, peak, then fall off. 2400 doesnt do that. It ignites, peaks, flattens out, then drops off. I think it is that flattening out that for me makes it so pleasant to shoot.
I have two hunting loads that have worked in all my .41s. A Sierra 210 Power Point/19.5g 2400. I used that load for years, killed a ton of deer with it. I use mostly now 17.5g 2400 with a CBPT 250GC in .41RemMag. That bullet has shot completely through the shoulders of everything I have used it on. Just about anything will shoot through a deer but I have used that bullet to kill 5 large cattle, a 600+lb cow bison, a 1800+lb Angus bull that had broken its leg and three feral cattle 1200+lb, 1400+lb and a monster steer of over 2100+lbs. Four were shot front shoulder at 66 yards or less with complete pass through. The big steer was shot square in the middle of its nose with the bullet exiting out the back of the skull just behind the horns. That one was shot at about 8 yards. The bison and the steer were shot with a .41GNR#2 the other three with a plain Jane .41RemMag. So dont overlook 2400 when you start load development for the 265g bullet.
