I'm attempting to simplify my 7.5-inch Super Redhawk .480 Ruger reloading by limiting myself to two powders and three bullets. Modest loads I have firmed up. I ask for assistance for hunting loads.
To shoot with 350-420-grain plain-base cast bullets while keeping operating pressures beneath 39,000 PSI, what single powder provides acceptable performance throughout the bullet range? If compromise is necessary, sacrifice bullets/performance above 400 grains.
Until yesterday I believed Lil 'Gun was the answer. In the thread, "454 Casull/Lil'Gun Cast Info Request," the consensus appears to be that Lil 'Gun burns hot, perhaps erosively, while yielding mediocre accuracy in .454 Casull cartridges.
