I have two rifles that shoot Barnes TSX bullets very well. One of them is a .30-06 that has averaged less than 0.5 moa for more than a dozen groups at 100 and 200 yds. Both neither of those rifles shot good groups with them until I was pretty much a max loads.

My conclusion is that TSX bullets can be very accurate, but are sensitive to both powder load and seating depth, to a greater degree than most other bullets I've tested.
