I've got a chapuis 9.3X74R. I just ordered some brass and bullets to reload first batch. I shot a case of factory loads to compare to my reloads. I love the thing and have shot several feral hogs with it already. It's light weight, has tolerable recoil, and really has the power to take anything up to cape buffalo (in my opinion. It has taken several ele's in its history). Someone mentioned earlier that it was analgous to the 35 whelen. I'm going to have to dispute this. I have both a 35 whelen and the 9.3 and find the 9.3 substantially more powerful. My factory loads shot 286 grain bullets at 2400 fps. The Whelen, at least in my experience, doesn't quite have the kick the 366 does. 35 Whelen's generally aren't loaded with anyhting heavier than 250 graines, and one can easily reload a 9.3 with ~310 grain bullets at roughly 2300 fps. This is not to knock the 35 Whelen, as it is my personal favorite cartridge.
