Diminishing returns in regards to being able to handle the increased recoil from the higher velocity/ higher pressure loading used is what I meant.
If a big bullet at revolver generated velocities uses a bullet constructed to break bones in the legs and shoulders, and does so at velocities generated in the 460 Smith and Wesson and 500 Smith and Wesson, than what more is needed?
A 454 Casull in the 460 platform and a 500 JRH in the 500 platform should also be sufficient. The 460 can shoot a 395 grain hard cast at about 1400 to 1500 fps depending on barrel length. And a 500 JRH can shoot a 500 grain to a sufficient velocity also. So what is the need for more and more?
