At the club I belong to, 300 yards but there is opportunity for much further on private land.
I purchased a quantity of the 168 GMM a few years ago for $20 a box. It can still be found for about $25 today.
That is what I'm finding too. After the first box of ammo through the rifle, I don't recall any group larger than .6 MOA, with the rifle now settling in to the .4 to .5 MOA range with this load. The photos of the 3-shot groups are the ones I saved to my PC at the time and still remains representative of how the rifle continues to perform.
Though accuracy remains a top objective, I'm also interested in Doc's info on terminal performance. So beyond the SMKs I'm also looking at the A-MAX and Nosler Accubond, both of which seem to provide great accuracy based on user experience I've read in various forums. Any feedback on those or other non-SMK bullets is appreciated as well!
