Not sure of factory but mine are best at .085 off the lands on the AFrame handloads.
It would be logical for me to start about there with the 180 A-Frames and also load some a little deeper (sense I've already tried shorter).
My 180 Scirocco load is a done deal at .087 off the lands. Just need to get the A-Frame load to an acceptable level and then decide which to take. Maye both.
Good to know about switching from ABs to Sciroccos with no issues as well. I go the other direction (from Swift to a Hornady 150 gr FMJ practice load) with no issues.
