aired-out....hate to break it to you, but unless you're very lucky, your rifle will not shoot well much beyond 400.
I have the very same rifle and it shoots 55 grain bullets just fine. It maintains accuracy at 400. When I moved to 600 I was just wasting ammo. A friend handed me some 77grain match bullets and the 12 twist is not fast enough to stabilize that bullet. My rifle just flung them all over the place.
I haven't tried 60-62 grain bullets, but the conventional wisdom still says they are not heavy enough to go 600+.
In order to shoot 600+ you will need an 8 twist barrel and shoot heavy bullets.....Check out this article....
