if you really want to wake up a .44 mag' Handi' with a good dose of power, why not try the 44/454 JDJ Woodswalker.....if the chamber will 'clean up'. SSK' advertises that they will help you 'wildcat' a firearm, so to speak.
As you might guess, J.D. Jones has taken a .454 Casull case and necked it down to a .44 mag' caliber producing 2100 fps with a 300 gr' Nosler out of a 15" barrel -- per "Cartridges of the World". It'll give you 2300 fps with a 240 gr' XTP' out of that barrel. It'll give you a little more out of a Handi', I would believe.
That's quite a step up, and the brass is more readily available than the .445 Super Mag' -- I believe.
The reamers, and dies should be available via:
