For the Mark VI I am using a custom gang mold made by Tom Ellis of Accurate Molds. The bullet generally resembles the profile of the MkVI service bullet, but with the nose truncated to a flat nose with 0.3" meplat diameter, which provides good stopping power on game, even at low, 600 fps velocity. The bullets drop .455" from wheelweights, and I had my gunsmith uniform and hone the cylinder throats of the cylinder to a .4555" all the way around in his Sunnen hone, which mostly removed the old pitting form use of the old corrosive military primers. load 3.5 grains of Bullseye pistol powder, which gives about 560-600 fps with the 262-grain bullet. I'll try to post some pictures.
