210 Berger VLD, Fed GM 215 M or a CCI 250 M, start with 74 gr of H-1000 and work up. I usually find a sweet spot between .005" in the lands and .010" off the lands.
I am getting 2916 fps with 77 gr in my sons 27" Broughton barrel. But work ou to this as I was working up a 26" Sendero the other day and it was too hot at 76 gr. Depends on the rifle.
