Finally got a chance to shoot long range with this bullet for my 308 Tactical this morning. Just as I suspected, this bullet is good only for paper punching and not much else. I thought I would be able to use them hunting but after recovering the remnant of the bullet in the dirt, there wasn't much to be desired (see picture below). Total jacket and core separation. The combined remaining weight of jacket and lead core was 130.5 grain. According to Exbal, the impact energy remaining at 737 yards, the distance at which I was shooting, was 862 ft/lbs.
The Exbal was right on target though as far as elevation is concerned. I was shooting at a rock, about a foot in diameter, at an elevation of 2602 ft. The temperature was at 59 degrees F and the pressure at 27.17" courtesy of my GPS. My first shot was about a foot low following the recomended standard pressure at altitude on the Exbal program , which was 26.89". I then corrected the pressure for my successive shot by inserting 27.17", the reading I was getting from my GPS, and fired three more times, hitting the rock twice. My average velocity is 2650 fps. I didn't have to tweaked the B.C on this bullet. It is right on the money also.
