If you are properly set up this challenge should not be too difficult, checking the list looks like you need an Anchutz (however you spell that) or a CZ varmit. Next you need a massive high mag scope so you can see the xhairs move when you breathe. then you need a set of fancy rests so your rifle stays steady. After that is just how much money you want to spend on different kinds of ammo.
Then the only limitation is the dude behind the trigger. Then you can play around with bedding, triggers, screw torque or new barrels till your hearts content.
The real challenge is the handful that have done it with sporter barrels, low mag average scopes, non premium or hv ammo, or shooting off the hood of there pickup IMO.
Hats off to the last few with the Mossberg and the Marlin, and the CZ scout with the Fed game shok ammo as well as the NS522 and the couple Savages.
Have fun, and burn up some ammo.
