eman308, The AA#7 is a good powder is a little fast for the heavier bullets. Here is some data for Accurate Arms as you can see 1200fps is a little out of reach velocity wise. No. 9 will get you closer.

That being said the upper loading of AA#7 is not athe rocket you are looking for but that pressure will go up quickly above the recommended max shown. Good luck!
