Hey, I could live for an entire lifetime shooting nothing but the .223 Normal or the .223 Ackley. And simply H-335 with 40-Ballistics.
I've killed as many prairie dogs and coyotes and most anybody and the .223 just works ... want an extra 50yards, Improve it.
I've learned one thing in my looong life; a GOOD man with the .223 is frickin' AWESOME. Same goes for the .30-'06. Don't need more and less is too little.
God Bless,
Steve
