2520 is fine in an AR; if anything it's a little slow in burn rate and may over-gas the rifle. The problem is your loads or the gun, not the powder.

Are your loads too light to cycle the action reliably?

Is the gas block aligned correctly, and is it tight?

Is your extractor spring weak, or the extractor worn?

Lots of other questions to answer before assuming it's the powder's fault.


Everything you mentioned is fine, 2520 is the only powder that has given me this issue, I may increase the charge slightly, like maybe .2 of a grain and see what happens.
