I have been shooting TSX's in my tikka T3 25-06 no problems with accuracy .
I found that they like higher preasures .Load closer to the max than lower end .
IMR 7828 SSC 57.8 gr. 100gr TSX bt. 3357fps.seated35 thou off
have loaded hotter . no key hole even at 500 yds.
You seam to be loading towards the low end even for non TSX bullets.
TSX's produce lower preasure than xbt's so to get the same effective preasure you have to load hotter . your load seams to be on the verge of min load requirements .
