Hopefully Doc will have some thoughts as to the terminal effects of the Remington loads. The Barnes TAC TX (30811) bullet penetrates deeply and performs well against barriers. However if you take a look at the 300 Blk gel test performed at Brass fetcher the Tac TX had one of the smallest wound channels of all the bullets tested. The average area in square inches of the expanded Barnes bullet was 0.17 with 20.1 inches of penetration. By comparison the Sierra 125 grain Pro Hunter delivered 0.31 square inches with 18.4 inches of penetration. The Pro Hunter also performed well against barriers.
