Last year was the first year I've shot Barnes bullets. I loaded the 180 gr TSX in front of IMR7828 for my 300 WM running at a slow 2815 fps. I took 6 plains game animals in South Africa including 2 kudu (168 and 225 yards), black wildebeest (271 yards), blesbok (70 yards), mountain reedbuck (125 yards) and common duiker (~30 yards). Additionally, I took a scimitar horned oryx (265 yards) and a blackbuck (~70 yards) in Texas and ended my season with a bull elk (150-200 yards) here in Colorado. Of all these animals, I never recovered a bullet. I did recover a single petal from the exit wound on the kudu that was taken at 225 yards. Only two of these animals required a second shot. I've been throughly impressed with the Barnes TSX bullets and the performance last year.
I've loaded a set of 168 grain TTSX to have a look at them. Although, I'm not sure why because I have nothing to complain about regarding the TSX performance!
