I use H110 in full house loads... like another poster said, it doesn't make sense to me to create "plinking" .44 Mag loads, so I've not tried another powder...
Remember, with H110, do not reduce your loads below max by more than 3% (this is a warning printed in the Hodgdon manual; the loads shown in my Hornady Manual for this powder adhere to the same rule)... and, as another poster said, Magnum primers are not necessary... my testing has revealed that Magtech 2 1/2, Remington 2 1/2 primers are the most consistent (for me, in my gun), though magnum CCI primers do increase the fps a little. WLPs work fine too, though I found them to be the most inconsistent in my gun with my loads. I load all my .44Mag loads with Magtech primers, cheap and good. Oh, and definitely agree on the strong crimp... unless you like flame-cutting your top strap!
