300aac blackout load data

I'll get what I have in the binder tomorrow for you. I remember them liking the 5774, imr 4227 and 1680 powders better than H110 accuracy wise- 16" barrel. They might do better with H110 in a shorter tube.

What's your barrel length?
 
This is a culmination of loads from many separate sources.

It's not listed, but my polygonal barrel liked 17.3gr of IMR 4227 the most. It's min/max can be found on Hogdgon's load center.
