I have tried TSX bullets in a bunch of my rifles, and all shoot them well. As long as you seat them away from the rifling they shoot accurately. I am currently shooting them in a 7mm Weatherby Magnum (140s and 160s) and in a 270. My Model 7 in 7mm-08 shoots them well, too. My 30-06 shoots them accurately, and probably other rifles I can't remember. The are concentric, and the relief grooves fixed the pressure problems the old X bullets had.
