I found an old Lyman shotshell manual and it lists AL7 for 11/4 loads only. Nothing heavier or lighter. Seems like 28 -30 grains depending on the hull was yielding 1200 fps with pressures varying from 7500 - 10000 LUP depending on hull and components. Most loads called for card and felt wads but the hulls listed are plastic. Not much help as the components are likely not available but may give you some idea.
