TH, I've had the best results with the Berger 150 gr VLD for my .270 Wby Mag Mark V factory rifle. Tried Accubond, but rifle didn't like them. The 140 Berger VLD shot well also. Did not try the others mentioned. Good luck
TH, please disregard my post, I misunderstood the distances you were shooting. 10 to 75 yard shots are very rare here in the west. We hunt antelope, deer and elk at greater distances with the exception of thick cover which is rare. My comments on bullets for your hunting application were not accurate. I can not suggest a load for close range with a .270 WBY. My apologies.
