Some interesting take-aways from your post: I often wondered if the longer barrel provided a greater muzzle velocity but according to the comparison done the shorter barrel has a higher muzzle velocity. I wonder if handloading with a slower modern powder would give the longer barrel the nod. Next, the two rifles swap having the best FoM back and forth at the various ranges until they're a virtual tie at 1,700 yds. As you pointed out, not much difference between the two.
