How can that be unless you are handicaping the 404 and promoting the 10.75x68. Capacity has a bearing and a smaller case can never equal a larger for performance unless there is a higher pressure in the smaller and that can not make it equal. What sort of pressures are you anticipating to get 2300fps-2350fps (RWS load) from the 10.75x68? In the same way a 30-06 can not be equal to a 300 Mag or a 7x57 to a 7mm Rem mag.

im thinking in the lines of the original load of 400 grains at 2150 fps dublicating the 400 jeffery, the numbers you are quoting sounds to me like a 416 rigby load, so you are allready playing a pressure game beyond the original limits.

now hornady is allready bridging the distance between the 20-06 and the 300 mag, with the light magnum loadings.

what you are talking with your RWS load(brigde between 404 J and 416 rigby) is the same that im talking about with the 10,75x68 and the 404 j
