For steel targets at close range, 180 gr. DEWC with 5.5 gr. AA#2. Pulverizes the bullet except for a little bit of the base that's squashed flat as shimstock.
For a load that's a step above SAAMI compliant 44 Sp or 45 ACP but doesn't have magnum kick or blast, 7.5 gr of AA 2 with 240 cast bullet. Good for about 1000 fps.

NOTE: 9.0 gr of AA 2 is a MAX load with the 240 gr bullet so all precautions must be taken to prevent double charging.
