I have shot the 45/70 guide gun, I own the 45/70 cowboy, Maybe
its just the way I hold the rifle. but that extra half foot in length
really makes a difference. I guess the sight radius of the cowboy
really means something to my eyes. The cowboy shoots so much
better than the guide gun I shot. I use 405 grn Rems, 350 Hornady,
400 grn Speer, and 300 HP from Hornady. they all shood well
thru the cowboy... the 350 is overall better thru my gun I think.
ya the Coyboy is longer, but I guess I am used to it. at least
I never got stuck in a snag with it out in the woods.
