I'm interested in hearing if any of you own black powder express oval bore rifles, by Charles Lancaster or others. How do they shoot? Any difference in loading for them vs traditional rifling or Henry rifling? Asking as I now have two, one in 450 3.25" and a second, slightly earlier rifle, in 500/450 3.25". Both are hammer doubles with Jones under levers from the mid to late 1880s.

TIA,
Chris
