I just came back from the range this morning testing loads. Two bullets tested were the hornady 300 spbt and the sierra 350 match king. The load for the hornady 300 is 111 grains of IMR 7828ssc at a velocity of 3200 fps. the sierra 350 is 108 grains of reloader 25 at a velocity of 3005 fps. The rifle is a remington 700 sendaro rebarreled with a Brux .375 1-10" twist 31 inch barrel.
