What velocities are you guys getting out of your 30-378s? I loaded up a buddies with 107grains of retumbo, berger moly 185vld, 10 thou off the lands and got 3680fps with a sd of 7fps. Gun has a 27 1/2in, 12twist schneider. This load shot great! No signs of pressure. Ohler chrony. Does this sound right? Seems really fast.
