2muchgun,
I've gone through several boxes of the 70 TSX, 62 TSX, and 62 TTSX trying to get them to work. Never got better than ~1 MOA on anything; I settled on the 62 TSX with Varget for a 200y max deer load but have moved on to the Sierra bullets for yotes and steel. Maybe I'll go back and try the 70 TSX with Varget, never tried that combo. I know that seating them deep (.08 off the lands, COAL 2.18") helped tighten up the 62 TSX.
I really wanted the Barnes bullets to work for some reason! Maybe I'm just being to picky....
