I know that it's a little late now Gator but don't forget about 2400 powder as well. Unless one is using heavy for caliber bullets (more than 230gr in this case) H110 won't really do anything that 2400 can't. The other benefits are that you don't need a magnum primer and you can safely use lower charge weights of powder. The later is something that is not recommended with H110/W296 powder.
Lately all the craze is to stuff the heaviest bullet one can find for a given cartridge into the case regardless of the intended use. I understand that there are certain applications where this is necessary, but for most uses a standard weight bullet of proper construction will be more than enough. Shortly after the purchase of my Ruger .41 BH I also purchased some real Keith bullets from Montana Bullet Works.
I wanted to see for myself just how good the ol' Keith load was for this caliber. Keith used 20.0gr of 2400 under this bullet, but folks claim that today's 2400 burns a little hotter now than it did back when Keith used it. So I consider 19.0gr as the MAX charge weight to be used. I statred at 17.5 and worked up to 19.0gr in .5gr increments. As I worked closer to 19.0gr I noticed that accuracy got better. At 18.5gr recoil was about the same as factory ammo and, the load hit to the sights and accuracy was a bit better too
I then loaded up the last 5 rounds that contained of 19.0gr 2400.
As soon as I touched the trigger my immediate thoughts were WHOA MOMMA
, the dang grips gouged a bit of skin from pinky finger. That load has all the recoil I ever want to endure from that gun. It was very accurate more so than the 18.5gr load but goodness the recoil is something else. Keith as well as others did very well for years with his bullets before heavy for caliber bullets became all of the rage. I don't see any reason why his loads won't get the job done just as well today as they did in the past.
I'd also like to add that the 19.0gr load was really cooking along. It hit a full 1" - 1 1/2" lower than the factory ammo and the 18.5gr loads.
