I have a stock 15" .460S&W barrel on my Encore which of course shoots the .454 Casull and .45 Colt. The Colt out of it is almost anemic while a 300 grain hand load in .460 is whoo-doggies stout. The .460 with factory Hornady loads destroyed scope rings until I went with a Talley 1-piece set up.

I would suspect the Casull to be stout but not uncontrollable. A handful, yes. I've read before; recoil is relative.
