Well, I was unsuccessful in getting a read on the chronograph, kept spitting out errors. Perhaps the light wasn't good enough. I'll have to try on another day.
Did learn a bit more however. Full power loads still kick, so I decided to shoot a 2x4 while hiding behind a tree. Fired 3 shots, all 30 grains FFFg Swiss with the Johnson and Dow conical just barely below the chamber mouth.
1st shot just grazed it. 2nd embedded itself next to the graze, and the 3 split the thing in half.
Now this is an old 2x4, but I'd still say that's gonna do some damage to a person. Blood would be spilled for sure. It is funny how quickly they start tumbling, so damage would probably quickly drop off with range.
Apparently if you need to do a combat reload you can cut the time of the swap in half. Reattaching the barrel is unneeded.
If I can get an FPS reading, I think figuring out velocity changes with a free moving cylinder is just a bit of math.
