Yes whatever works well for you& your conditions would be a good choice Lotsa guns can shoot 25-400 yards well enough. 30/06 & all its off shoots cal to start with.

But i dont think the navy & army etc chose the 45-70.govt because it was a short range brush gun.Believe there where some 1,000 yard shooting compations, comparasons & tests done before it was adapted.
Fly like a brick...its the landing part thats ez.
