Since they are both magnum pistol cartridges, I'm sure that H110 would fill your requirement nicely, but at near-max pressure and velocity only! Trust me, I just got done with a series of under-powered H110 loads in my .454 Casull, you don't want to under-load H110. For plinking loads I'm sure Unique would work, but you don't own a .44 mag and a .500 for plinking, do you?
