Sounds good, I threw in some .224 75gn Amax's bullets for you to try - only 10 but might give you a general ballpark. You might know of this site already, great info: http://www.accurateshooter.com/cartridge-guides/223rem/
Awesome! Much appreciated. And yep, I`ve found that site to be very helpful, I`ve read most of the cartridge guides a few times lol.
