Paul, while you are waiting for your rifle to be built, it might be interesting to do some more fundamental, basic ballistics thought experiments with a ballistics program. What about some basics like the effect of bullet weight and B.C. on your target. What about point blank range, sight adjustment changes, bullet time of flight, etc. There might be some real surprises, given the rainbow-like arcs on 45-70 type calibers. Hitting a PD at distance would be fun, but I bet it is a lot harder than shooting a steel buffalo at 500yds, especially with non-optical tang sights. Think artillery.
