Do a 284 Shehane. I built my F open rifle in that caliber. It's consistently 100-150fps faster than a standard 284 with the same barrel length. 3.5gr more powder than a std 284. I'm shooting 54gr H4831SC and a 183 SMK at 2850fps for fireforming. I'm shooting 57.5gr H4831SC with the same bullet at 2973fps for my target load. Both loaded in a long action 3.250" COAL. Keep in mind these velocities are out of a long barrel (32" Krieger). Only downside is does are expensive but Winchester brand 284 brass is good stuff.
