That is a good deal. I had tried a Freedom Arms 454 Casull and liked the revolver, but the thing about that cartridge is that it has such high pressure that to has too much a fast recoil that it becomes fatiguing to shoot. If you hand load, use Casull brass and load it to about the pressure of a 44 magnum, then it will shoot with a bit more energy than a 44 magnum or a hot load 45 Colt and still be manageable. If the full house load does not bother you, fine, but that is why fellas sell them off, it is just too much gun for most men.
BTW: I like the 480 Ruger better, but it was not out in the Blackhawk I perfer and now I am too old to fool with a new heavy load.
