I am just trying to learn here. I have a .223 with a 1in9 twist and a 22 inch long barrel. I just bought some Hornady .223 75gr ammo to use in it. I was reading an article on another site that suggested that 75gr was right on the edge of what a 1in9 twist is good for. In the article it was talking more about shorter barrels like you get on assault rifles (AR-15) and I was just wondering if the same holds true for longer barrels?
