I'd also suggest the 458 socom.
Something to consider (if it was already mentioned, I missed it) are the hunting regs in your area. Nebraska, for example, has a minimum power level requirement for rifles--900ftlbs at 100yds. That's a level that only a heavy (>400gr) bullet will achieve at subsonic speeds. But, they also make exceptions for 357 magnum and 45LC rifles. No mention of 44mag though.
