Drifting the sights... get some paper and draw a diagram. Front and rear sight make a line, goes way out to the target. which way to drift rear sight to have said line also contact bullet holes ... drift to the right to move holes to the right

I'd shoot at 25 to get your left/right mostly on, then move to 100 for vertical on the 45-70. I'd sight the 357 and 44 in to be dead on at 75 - little high at 50, little low at 100 (pushing it for 357, just on the edge for the 44)

A quick search shows that with you 1.5" high at 50 yards should put you close to dead on at 100 with the 357 and 44
