I acquired some of this ammo for the 8x57.
Imagine my surprise to find the 196 [or 198, can't remeber which] grain
bullets clocking 2675 avg across the 'graph.
And....shooting right around 1¼ moa right out past 300 yards.
Then, I bought a 300 Win Mag from a local guy, who tossed into the deal
a couple of boxes of 180 grain PRVI ammo.
It shot 3 shots into 1" regularly at 100, but I shot no game with them, nor did I run any across the 'graph.
My take is that it is not bad ammo.
