A 300 RUM should easily be able to push a 210 VLD @ 3100-3150 fps. The Berger VLDs are advertised to expand down to 1800 fps. @ 3000 ft elev, the 210 out of a 300 RUM should be a 1K plus cartridge, almost to 1100 yds.
Man! Now I really want a 300 RUM but looking forward to the new 338 VLDs that are coming out soon(within a year hopefully)
1097 yards is 1000 meters so that load (210vld @ 3125fps) pretty much meets the expectation.
