Thanks Chris,
The 600ok is a straight-walled wildcat round with a head size of the 505 Gibbs with a belt for headspacing on a 3" case. It's capable of taking a 900gr bullet up to 2400 fps if you wish to. I'm going to keep mine down around 2100-2200 as that's plenty and pressures are lower. This rifle is built by AHR (American Hunting Rifles) from Hamilton Montana on a CZ magnum mauser action which they then modify. This one has a forward scout-mount system in case I want to use a scout scope as well as the integral receiver mounts plus NEGS 2 blade express sights. They steel glass bed the entire stock channel as well as the double bolts.
