    223 and AA1680

    Has anyone loaded 223... 55 grain with AA1680? I realize it isn't one of the better choices but I have 17 pounds of it and don't load for 300 black out. My preferred powders are fairly well extinct at the moment. I have AA load data from the 90s and that's when the powder was manufactured. I've tried some in two ar's and one will function well at 74 yards and one won't recycle. Just curious as to others experience with the two. Thanks.

    That is a lot of AA1680. It is great in 22 hornet and magnum handgun but my experience with it ends there.

    I’ve read about people using IMR4227 with cast bullets in 223, so it might work. But I personally don’t even like 1680 in blackout. It’s loud, dirty, and underwhelming.
