So I stocked up on some 2230 to go with winchester brass, CCI 400s and Horniday 55 gr FMJ's. Then when I went to the Horniday manual it is not listed for that bullet type. Does anyone have a good receipy so I can back it off 10% and start testing? Thanks guys. |

work up loads on data from AA http://www.accuratearms.com/data/Accurate%20v322%20web%20publication.pdf |

AA-2230 is one of my favorite 223 powders for 55 gr bullets.
I use 25.5 grs AA-2230 in LC brass, Win SR or Wolf SRM, and seat to mid cannelure. I got pressure signs at 26.0 grs, and backed off .5 gr. So 10% less for a start load would be 23.0 grs with a 55 gr FMJBT. ETA, Looked at Accurate Powders site. Their data shows start at 22.5 grs, and max at 25.0 grs for a 55 gr. Go with the published data. I am relaying what works in my rifles. YMMV |
