There are a bunch of good powders for that round. I`ve used alot of Blc-2 and always had good luck with it. There was a bunch of AA-2230-C powder on the market cheap and I bought 48 lbs. of it sso that`s what I`ll be useing for a while now, but there is no real good data for it so if your not used to working up loads without good data it might not be a good choice for you, but it is in the right burn rate for that round.
