Most times I use Sierra 75 grain HPs or Nosler 55 grain BT's. Propellants are H4350 or H414. Mag primers always with the H414 to improve accuracy, and either bullet will produce nearly single hole groups @100. Measured velocities with worked up 75 grain loads are in the mid to high 3400's; 55s clock in just over 4000 fps... Crows literally look like puffs of smoke when the 55s connect, and the 75s are absolutely devastating to ground squirrels, rock chucks, and groundhogs in my experience at very, very long range.
My particular rifle never shot IMR 3031 or IMR 4064 nearly as well as the two mentioned, so it seems to like to live on the "slower" end of high load density, slower propellants. FWIW, my rifle also becomes more accurate the faster the velocity.
