I've used Barnes TSX on three trips and in .308 and 9.3 to harvest about three dozen animals. The only issue I have is blood trails are a few yards befor starting if there is a blood trail at all. Had a well hit Wildebeest leave no blood and was found the next day. A broadside lung hit waterbuck went a long ways and only left a blood trail the last 10 Yds. Except for my Montana Mule deer I've used TTSX on deer, boar, antelope and coyotes for the past four years.
