Bigfoot;
I haven't shot his gun, and I don't have a program that generates recoil energy numbers either. But, here's the data.
My .338 is at 2900 fps muzzle with a 225 grain bullet. The Hornady manual calculates that that combination delivers 4201 ft lbs of energy at the muzzle. Speer 14 gives a max load 2583 fps with their 270 grain bullet for the 9.3 X 62.
Since Hornady does not produce a .366" bullet, there's no direct data in their ballistics tables in book two of the 6th edition. So, derived data from the .375 round nose 270 grain bullet at 2600 gives 4052 ft lbs of energy, 2500 fps gives 3746 ft lbs, both at the muzzle.
Using that, I feel I can say that the 9.3 will not recoil as hard as my .338. But, it's also not going to be far behind. If you're at or near max load, you will notice it when you turn one loose.
