I get the same performance, with the same caliber and rifle, same load,(62.5gr@3200fps) using 140 Ballistic Tips or Accubonds, same POI. I have always been surprised on this site that the Model 70's get very low exposure. I have had several over the past 40 years of all generations including a couple of pre-64's. They have all shot equally or most of the time better than the Reminton, Savage , Kimbers, etc. I have owned....right out of the box. I expect it is the receiver design, making it more difficult to rebarrel and bed than the round actions which the gunsmiths prefer.
