I have a Savage 10FP law enforcement series .223 heavy barrel rifle. Its a very accurate gun. well its for the swat team and such so of course it has to be accurate. its a sniper rifle basically! lol. the .223 is also what the military uses in their rifles. a M-16 is calibered for the .223. that is my opinion and i would reccomend. it lays out mostly groups of .5" and less most of the time sometimes there is a few thats about 1" off at 200 yards which isnt bad at all!
