I have a 35 Whelen, 9.3x66 Sako and have owned and hunted with a 375HH. The 9.3 is the best of all worlds, recoil is similar to a hot loaded Whelen and thumps like a 375, actually "on target results' are the same as with the 375. With the 9.3 x66 the factory powder is VV-550 and uses 71gr with the 286gr and 73 gr powder with the 250gr bullet, with regular powder i am hoping to get like results with around 66gr powder , lowering recoil a bit more.
