I use enough 4227 to power a 300gr cast performance flat nosed gas check to a very accurate and clean burning 1350 fps, recoil is very nice in the big FA revolver, and it'll shoot through anything I'd ever point it at, I also use CCI-450 SRM primers.
That said, I did find a box of 50 and a shell belt with my old hellbender load for my FA 454, it's the 335gr Cast Performance WFNGC at 1586 fps powered along with WW-296, that's the damn load that caused me to have to send my revolver back to FA for a new set of grips, they began to splinter at the grip frame, not fun!
