Before I begin this is what I am using:

Accurate Powder 2230-C (Equal burn rate to 2460)
.223 cartridges (all kinds)
CC small rifle primers
Sierra 69 gr HBPT MK bullets (Mollie plated)
AR-15 , 16" barrrel. 1:9

Collaboratively, manufactures and reloading books say to start with (Accu)21.5 gn with a max of 25.0 gn. Well today I went out and shot ten rounds of each with 23 gn, 23.6 gn, 24 gn and 24.6 gn to see which made the best grouping for my rifle. All of which, failed to eject and re-chamber a round. So after a half a day of frustration, I went back home and pulled out some factory rounds from three different companies and found out they where all around 52 gn of powder. So does anyone have any ideas or ways to solve what is going on? I thought about adding more powder, but I want to make sure I cover and research any areas of concern before sticking a fatal round. I never had these problems with my .270 WSM when dealing with recommended grains.

Also keep in mind right after I shot those rounds, I shot normal factory loaded ammo and everything worked fine.
