I bought a used 700 308 from pat for my boy. He had the load data for it and I used it. 45.5 grains of varget and 155 grain scenars. Maximum oal. This chronos right at 2800fps. Shoots very tight groups. My boy shot a big mulie with it at 320yds.through both lungs and a 2inch hole out the shoulder. The buck hobbled about 60 yards and he shot him again. Bullet hit about 4inches back from the first one.not as big of an exit hole, as it did not hit a rib going out. These bullets expand fine, but are thicker jacketed than bergers. Excellent accuracy.
