42 grains of reloder 10x gave 2200 fps using 275 grain woodleighs. This was a 358 winchester and a 20 inch barrel.
I'd imagine that RL 10x would work even better from the 9.3-308, Allowing less pressure, and maybe even more powder capacity.
Anyhow, these big woodleighs sailed through two massive bull moose. One moose about 100 yds away, the other about 150 yds away.
I can't see why the 9.3-308 wouldn't do the same?
Some of the factory 9.3 ammo that I've shot Alaskan game with, was severely underloaded:
286 grain lapua mega: 2150 fps.
286 grain nosler custom: 2200 fps
They killed just fine, even out to 200 yds.
So many years of hunting Alaska with the 358 and the 9.3x62, I could see no difference in killing power. The only difference, was that I took a 400 yd shot on a caribou, and a 500yd shot on a bull moose with the 9.3x62, that I wouldn't have taken with the 358 win.
Anyhow, just something to think about: actual experience vs hypothetical thinking out loud. This 9.3-308 wildcat will do just fine.
