I am looking for a new 223. I currently have a ruger american predator and its not cutting it. I want a gun thats very accurate, accutrigger style trigger, and lightweight. But I also want to be able to shoot all day with it and not have the barrel heat up (I get about 5 shots in my Ruger before accuracy goes way down due to heat). But want it light enough to hunt with so i don't want a full blown heavy barrel. Any ideas?
