Grouped well for me with Barnes Vortex factory ammo (165gr TTSX), between .75 and 1 but I didn't record a measurement at the time as I was only looking for "minute of deer".
Perfect condition, just don't need it and looking to fund another project. Never taken to the woods, range session twice - mounted on 6.5 CM. Have original box, manual, packaging etc. $475 shipped. Vortex Pro Series 30mm Rings pictured in photo available for additional $75 if interested.
Rifle is in like new condition. Purchased for a hunting trip last season, 20 round break-in & zero, barrel isn't even fully broken in yet. Has stayed in the safe otherwise. Decided to stay with my trusty .300 WSM and sell this one to fund a smaller caliber project. Scope is not for sale...
