Lately I have been using Noslers 250gr. Partition bullet in my 44 mag with excellent results. Nice expansion with that penetration of a cast bullet.

To get back to your question I think a nice cast bullet (NOT necessarily "Hard Cast") of 200-250 grains sized to 0.431" sitting in front of a stack of WW231 or Unique, or even as low as 17.5 grains of 2400 will fill your bill for most of the shooting. 428215 is great IF it will shoot out of your gun for plinking and playing and can be pushed if need be. Something just a little hoter would be 240-255 cast in front of AA#5, AA#7, HS7 or some such. I would also have a load of say AA#9, 20 grains plus of "new" 2400, WW296 or H110 pushing the heavier bullet when protection was really my concern.

Contrary to modern "wisdom" I have had an issue with leading in a 44 one time . . . relatively mild loads with a VERY "hard cast" commercial bullet.

All that blathering on to say 8.5 grains of Unique behind a cast bullet!
