I Had my stainless old army out to test a "heavier" load to be used on a Missouri wild hog / whitetail hunt. The gun in question is an 1985 7 1/2" with adjustable sights. I threw 42 gr Pyrodex P from a Lyman #55 powder measure through a drop tube, with a 255 gr hard cast rnfp 45 colt bullet seated on top. That is the maximum I can shoot, and still be able to seat the bullet's nose below the cylinder face. Bullets were obtained unsized at.455 dia., and I made a basic die to size only the bottom bearing band of the bullet, to facilitate straight loading of the bullet, which is critical for accuracy. A small amount lube on top of the cylinder face, Remington #10 caps-(best fit), and a clover leaf group was shot at 25 yds. Suprisingly, leading was not an issue, and the gun shot a tight group, more than acceptable for a 40 yd and under hunting situatiun with a black powder pistol. The front sight has been changed to a higher dimension to compansate for heavy bullet recoil. Now, do I back bore the cylinder to gain an additional 5-8 gr more powder space, gaining 75 more fps? This particular load in the stock cylinder chrono's around 1180 fps for around 800 foot pounds energy. Anyone want to go Missouri way?
