I use Redhawk. All Rugers are same - much stronger than other guns. I have spent last year working up loads for my 45Colt, now doing 454Cas. I can give you my data with H110 and 2400 powder if you want. It is the only powders I use; there is none better. I have pushed 300 grainers to 1200, 250's to 1400. My little Redhawk hasn't blown up in my hand yet.
