I built 3 AR15s in this caliber for some ranch managers as they want the 224V for coyotes/deer/antelope.
They all have a 22", 1/7" tw bbl, rifle length gas. Testing many loads/powders I found all 3 will put the 53g Varmageedon into .333" to .600" groups at 100 yds.
The federal fusion factory 90g load runs from .870" to 1 1/2" at 100 yds, seems they just don't like to print better for the factory load.
75g Hornady BTHP match sticks to .750". 75g amax the same, 60g vmax stays a tad under 1". Testing the 68g hornady BTHP and 80g sierra BTHP next.
Powders Ive tested, CFE, H414, X8208, H335, blc2, super performance,
