What happiness looks like
A revolver that runs clean and has no cap jams makes for a great day.
I was able to test Arbutus Black Powder in a couple of my guns, and while the velocity wasn't the best I was happy with how it ran cleanest in my 36 Navy. With 25 grains of 3F and a .375 ball it was consistently right at ~1070fps accuracy was good at 25 yards freehand, and I was able to shoot 6 full cylinders without stopping to clean fouling or pick out cap jams. Caps stayed mostly intact and attached to the nipple, typically they blast into oblivion!
In my .58 Hawken 100 grains 2F produced a sedated ~1520fps with a 280 grain ball, but the benchmark for Swiss was only ~1460fps.
In the .54 Mortimer Flintlock 100 grains 2F produced ~1620 fps with a 230 grain ball, and Swiss benchmarked at ~1540 fps.
I didn't use my usual chronograph, but an old Chrony F1, I typically test with my Magnetospeed V3 chronograph but had no way to mount it on my pistol. I'm curious to recheck the rifle velocities with my usual setup. Was limited to the 25 yard range today so no point in putting the rifles on paper.
