So my Sako 7mmRM shoots the 150 TSX to my satisfaction at .7moa very consistently using 64.0gr 4831 and Rem9.5's. I have not tried the TTSX of the same weight, but like the idea of even a slight increase in bc from .408 to .450.
So my quesion is do I have to plan on significan load development work, or is there a high probability my current load should group as well? Don't want to mess with a good thing and put more loads down this barrel than necessary just to tinker. This gun, oddly did not like the TSX 160 FB near as well.
Opinions, especially real life from anyone going TSX-TTSX or vice versa.
