Chuck Norris doesn't go hunting he goes killing; because hunting implies failure. 
I ordered the Chuck Norris Roundhouse Killing system a couple of years ago... it's almost too effective... as Hoytstaffinfection says "that's not hunting".
Now, I shoot a .300 RUM out to 1k all the time... the schitt ain't rocket science. Even guys with little to no experience can take my rifle and hammer on milk jugs at 600 with relitive ease. Just dial in the proper dope... hold the X on the target... and whammy! The tough part is shooting your ACTUAL drop chart and knowing the small adjustments to make for shot angle, and wind.
I don't advicate taking a rifle out of the box and shooting it at critters 1/2 a mile away... but shots like that can be made. I also don't advicate shooting at 200 yards if you can't hit stuff at that range... but most guys will take that shot no questions asked... regardless of their ability. I don't see anybody ranking on those guys. Bottom line... KNOW YOUR LIMITS... 100, 200, 500 yards... whatever... but the sign of a true HUNTER isn't the shots he makes, it's the ones he passes up.
I know I can shoot my RUM better at 600 than most guys can shoot their "hunting" rifles at 200... but that's what I practice. I know my limits, I pass up shots... but I'm ready to make the good poke too... I guess that makes me an unethical killer.
