With a Ruger super redhawk 44 Rem mag, with 7 1/2" barrel, and say shooting Winchester 240gr Jacketed soft point ammo. With the open sights, In general What kind of accuracy could you get at different yardages? Or to put it another way, approximately how far could you shoot a 3" group? I realize that there are many factors that would affect this, but just in general/ average shooting.
