Did you size the hammer first Chris? Makes a huge difference to downrange BC. AA being softer are far more sensitive to hammer size than the much harder JSB variants. I've found that JSB batch 13 seems to respond best using a 2lb ball pein that has been sized to 1.866 inches (+- 50%) and chilled to 8 degrees centigrade but only if your barrel twist is 18 inches and it's Tuesday.
Hope that helps
