Re: Where to find 5.56 nato load data?
5.56 brass is identical to 223 brass, same same. Most load data for service rifles is nothing more than 223 data with heavy bullets, 69gr and above with 1-7 to 1-9 twist, still running at 223 pressures of 55K psi.
Email Johan at Ramshot/Accurate and ask him for load data running at 5.56 pressures. You should include your choice of bullets.
