Just read another article on this--apparently this is a joint effort between Federal and Sako..

It is known apparently by European hunters as the 9.3x66mm Sako--

The article suggests basically this is basically a 30-06 type case necked up to accept 286 gr. .366-inch bullets--rated by Federal at 2550 fps.

The article states it is between the 9.3x62 and the 9.3x64 in terms of muzzle energy..with it producing only 150 foot-pounds less then the .375 H&H.

For more info read the March issue of Shooting Times--page 60
