This morning I loaded up the last 7 bullets that I cast in my original Winchester mold. Powder charge was 2.2cc (about 35 grains) of Swiss 3Fg. I also resized some of the .430 200 grainers that I bought from cowboybullets.com down to .429, and loaded 25 of them them on top of 23.5 grains of Alliant Reloder 7.
Because of Reloder 7's relatively slow burn rate, it offers the potential of duplicating or bettering the original ballistics while keeping pressures within the limits of the 1873's toggle link action. If accuracy is acceptable this should make a good hunting load.
On the other hand, Reloder 7's slow burning rate means that it's probably not a good choice if you're loading cartridges to be shot in revolvers.
I'm hoping to chronograph both loads, along with some of my handloads with 8.6 grains of Unique next weekend.
While I was in reloading mode, I decided to get myself a digital scale, a Frankford Arsenal DS-750. It will be verified with my Lyman calibration weights and checked against my Redding No.2, which is a great piece of equipment. The digital scale will be easier to read and take up less room on my bench, however.
