Hornady does have a unique blend for their 6arc ammo. After studying the arc powder under 10x magnification and comparing it to CFE233 and Superformance I see very similar powders. They all use balls in at least 4 sizes with the larger ones lightly flattened and in different quantity for each of the sizes. I am guessing the different size balls are of different burn rates and Hornady can blend them to the need of a particular cartridge. The arc powder blend appears to be closest to Superformance and I really cannot tell any difference between the two. I am beating the factory loads in accuracy with W 748 and CFE 223 but cannot match the velocity. I really want to try the Alliant Power Pro 2000MR as the listed loads from Handloaders magazine show it gets more accurate at the higher charges.
