My Dad has owned a 760 in 270 Win. since the 60's and never had a problem with it. I have done a bunch of load work with it, and I am impressed with the accuracy. He purchased it because he shoots left handed (left eye dominant).
I took a 7600 and had it rebored/chambered to 338-06 and have zero complaints with. Same statement as above applies to this rifle in the accuracy dept.
I shoot bolt actions almost exclusively, but when I pick up the pump, it is second nature since I grew up using pump shotguns.
As far as SA/LA, I would go with the LA. Even though most people think of these pumps as short distance "woods" guns, I have seen my dad consistently make 250-400 yards shots. He currently has 4x12 Leupold on it. But we hunt in western SD where the distances can stretch.
But handle both and go with what feels best best to you and personal preference.
