i didn't have the Precision data handy, it may have discontinued powders- I fortunately will never run out of 7625
I know one of my books (maybe Lyman) has a light bismuth load for AA hulls I have fit into hulls cut to 2 1/2 - I am guessing it used longshot - and one for 2 1/2 chedittes
if I find it I will post it
BTW - why 1150fps? the Hogdon data has low pressure loads under 8k but at 1350fps
