My Blaser R93 7mm STW seems to like the 150 gr. Barnes TTSX with 81.0 gr H1000. It regularly shoots .5 MOA or less at 3250 fps until I run out of ammo. My headspace is a bit generous so if shooting same (unlikely as mine was a run of one since they had stopped that chambering when I purchased mine) make sure to check and adjust sizing die accordingly. Good luck.
