Changing Ammo/poa

[Catfish]

It is very commom to have a large difference in elevation from one load to another. When going from my plinking ammo in my Ruger Super Balck Hawk my point of impact will go up over 1 ft. Doing the same thing with the same ammo in my El Dorado the point of impact will go down close to 1 ft. Velosity, barrel lenth and recoil all seem to have an effect on where the bullets will print.
