i was wondering if anybody has had good results with aa2230. i picked up a ma@i used upper from my local gun shop to play with. it has a 24' bull barrel and with a 55 grain horn. fmj or v-max fb i was getting velocities in the 3450 range with either 25 or 25.5 of aa2230,i'd have to check my notes but sieera says max is 26.1 though they're saying in the 3000, 3100 range for that charge. i know they used a 20' colt but i don't think the barrel length is giving me that much.both bullets shot great with the 55fmj slightly under 1/2' at 100yds. the primers look great and the velocities are good so i am going to see how fast i can push them. i also have a 20' rra h-bar i will check them in. if anybodys played with this powder please share with me.
