You can find out more in A-Square's reloading manual entitled "Any Shot You want" which can be purchased at a slight discount through http://www.alibris.com. Basically the round is a 460 Weatherby shortened to 2.5 inches of case length pushing a 500 grain bullet at 2420 fps. There is also a 495 A-Square which is the same case necked to .510" and pushing a 570 grain bullet at 2420 fps.

The problem with these rounds is that a Mauser needs extensive modification and a new magazine box to feed these cartridges. Also, if the Mauser is not of recent production, pressures may be too high and can cause lug setback.
