My experience is the opposite from most of yours, I have never shot partitions but I shoot Barnes TSX in 7mm-08, 300 mag, 270 win and 270wsm. basicaly anything I shoot Elk with, and in all of these guns TSX was the best grouper of all I tried. You do have to load them from 50 to 100 thousand off the lands, I dont know why but they like to jump. which is great because that makes them easier to get in the magazine. I dont buy them for deer, antelope or coyote guns because I cant afford to practice with them. Last years 270 wsm took an elk at 250 yards and I recovered the TSx on the opposite side against the hide. It was 140 gr and afterwards it was a 137 gr. So I guess except for the price I am a fan of Barnes. I also have no more fouling than with any other.
