Holy crap! LOL I have a nearly identical setup, even a Lefty
I'm running a NightForce 20moa base, Griffin Armament rings (came free with the scope) & a 4-16 PST.... great minds
Interesting report on the ammo, mine LOVES the 120's & generally doesn't shoot the factory 140's worth a hoot. It was perty fouled though, i've since given it a good cleaning & I intend to retest.
