Supposedly, the Endurance Package they came up with years ago makes them able to withstand lots of full-power loads. The Redhawks are bigger and heavier, but whether that translates into durability, I can’t say. Certainly it makes them easier to control and less painful, given proper grips.
Can’t imagine why anyone would need a lot of such heavy loads. A few for special “occasions”, sure.
Maybe an X-Frame would suit you better: .460 or .500. Either should easily handle a load similar to what you specify.
