I have a Stag in 6.8mm. 16 inch barrel , 1 in 10 twist, SPECII chamber.
I mounted a fixed A2 stock and a fix 6 power Leupold scope.
I hand load, but have also fired 200 rounds of factory ammo for chronograph testing.
My loads using SSA brass usually give 2,550 fps for a 110 grain bullet, 2,820 fps for a 90grain bullet and 2,250 fps for a 130 grain bullet.
I can achieve groups in the half inch range with some loads and around 1.0 inch with many loads.
I bought mine as a test platform to work up various hand loads. It would be fine for deer size animals if you live in an area without any large predators.
Unfortunately I live in a place where it is a marginal caliber for most game critters.
I will be selling mine, with 500 rounds of loaded ammo and 500 pieces of brass, plus dies.
