It's Magnum here. Great to see some more shooters of this late great big game calibre. I load AR 2213SC (ADI, Australian powder). They make it for the North American market and it is packaged as H4831 there. My pet load is 75grs behind a 180gr bullets (Hornady stock # 3075). This load has been chronographed out of a 24" barrel at an average of 3,105 fps. The load is hot but not excessive. I am very satisfied with how it shoots.

I am going to shoot tomorrow (and chronograph) a load going another grain (to 76 grs in 0.2 grs steps). I'll post the results then.

Do any of you have any load data for AA-4350 powder and 165gr bullets? I have been using 69grs of IMR4350 and have gotten a 8lb keg of AA-4350. Thanks
