It's a newer one, 2009 581 with premium ammo. I'll give you the fact that its not that tight with plinking ammo. First round on a coyote always makes its mark. That's also one year with only a bore snake ran thru it occaisionaly.
I had to take the rifle apart to install a muzzle brake, then of course re zero.
It was shot prone supported with a range bag and rolled up jacket for extra support. The rifle was fairly warm.
