Re: 300 RUM or 338 RUM?? Which and why???
I shoot a 300 rum, 210 vld bergers .631 b.c. @ 3125 26" bbl sendero, 20.5 moa to 1000yd using 200 yd zero, shot whitetail doe at 1007 yds with the 210 vld, broke both front legs just below the shoulder also got part of one lung and aorta left a 4-5" exit wound she ran about 60 yds on her hind legs plowing the hayfield leaving a 3 ft wide blood trail.
Shot another doe @120 yds with 210 vld to check for possible bullet blow up after so much expansion at 1000 yds, hit back edge of onside shoulder quartering away shot and i just about decapitated the deer 8-10" exit wound through base of neck severing the spine .
In last 4 yrs i have shot 4 other deer from 450 to 650 with 150 gr accubonds and all have gone down quickley.
My friend has a 338 edge and has had spotty expansion with the 300 smk on whitetails with some deer lost, i would highly recommend the 300 ultra
