I have recently assembled a 22Nosler AR. So far I have only shot factory ammo and while it shoots well, the brass is a mess. Burrs and extractor marks on 50% of the brass. I have read elsewhere that a slower powder eg H380 could be the answer and I see load data for 70gr bullets. Has anyone loaded up 55gr with something like H380?
I have an adjustable gas block on order but from my research it seems like the powder could be the key.
Thanks
