Well, starting to load some 454's for my Super Redhawk, and in reading, I find that, in order to load up to max speed, I need special hard bullets that will take the "heat". I had thought it would work to just use my 45 long colt bullets, and it would work as long as I keep to the limit shown for those bullets. I will normally use the lower loads, around 1300-1400 fps, but would love to have some of the real hot loads for special purposes. Does anyone know the best place to get some and what works best? Thanks, wallacem in Ga.
