Ridge Runner, you want to shoot a full grown bull moose with a .223 you better have at least one of 2 things. Unholy marksmanship skills or a really good will left with a good attorney. I've seen a mad moose, and you can bet your bottom dollar I would want something bigger than a .223 leaving a hole. Even hunting with a 1 3/4 inch 3 blade broadhead will make your butt pucker.
