That's good news guys. The was powder recommended to my by the staff ballistician at Accurate when I sent him an e-mail with the parameters I want. I told him I was looking to fire a 405 cast at around 1100-1200 FPS, so he recommended that powder & some loads.
24.3 gr are supposed to give me 1225-1325 FPS, and 27 gr are supposed to give me 1300-1375. This numbers are based on a 24" barrel.
However, I realize the the staff ballistician might be just a little bit biased regarding the effectiveness of his product, so I thought I'd get some feedback from some folks that have actually used. And as usual, GBO has provided me with the info I need.
Thanks a bunch everybody.
