I've been shooting the 210 VLD's @ 3,200 ft/sec for awhile but I'm curious as to how flat (comparatively) the 168's would be over 800-900 yds. The load would be used for whitetails and/or antelope. Realisticaly, how fast can the 168gr class bullets be fired from a 300 RUM? The printed sources seem to list very modest velocities for most bullet weights in the 300 RUM. I'm currently using a 27" Broughton.
