Not the article I was after, but just as interesting.
Once the bullets had been cast and the crew had had sufficient time to recover from this particular ordeal, the silver slugs had been turned over to Cotterman, who had complained that he would have to resize them. They had been cast in a 240-grain mold, but when he started measuring he found that the silver bullets only weighed 225 grains each and that instead of measuring .454, the size of the mold, the bullets had shrunk in their making, thus measured only .450.
This presented some minor problems. They were going to fit a bit loosely in the barrel, and in doing the loading, Superdan had to put one hell of a crimp in the case even to hold these bullets. Used were Winchester .45 caliber Long Colt cases and CCI magnum pistol primers.
"Tonto digging for fired slugs. At three bucks a bullet, this was the most profitable operation."
We then loaded up the Peacemaker with the loads carrying the commercial black powder offered by Hodgdon's and let fly at the chronograph screens. The time the bullet made its way out of the barrel ahead of the 40 grains of FFFG. We found that it was being propelled along at 804 feet per second. We fired several of these three-dollar bullets and came up with an average of 802 fps on the shots that didn't louse up the chronograph with black powder percussion. Then, for comparison, we fired a modern swaged hollow point bullet, this one of lead and weighed 200 grains. It tracked through the screens at 733 fps.
