If you want less recoil and less go-power than the real big boys, buy a .44 Mag. You can shoot .44 Special "mild stuff" too.
Or, if you want more versatility than.44 Mag, shoot .45 Long Colt or .45 LC +P in your .454 Casull gun.
You now have a choice of heavy but mild, or about .44 Mag & .480 Ruger power, or "real big .454" go-power in the same gun.
You are stuck in limbo with a .480 Ruger "orphan". .480 Ruger is all it does. An idea whose time never came.
It was a cartridge nobody wanted. Or needed. Ruger dropped "a dud".
I'll bet Ruger marketing types foisted this off on "their engineers".
And, we haven't even got to the .500 S&W or the .460 S&W real big boys yet.
I forgot to disclose I'm just one voice in the wilderness expressing my ideas.
And, I own several ".45 Long Colt" firearms.
And, a Ruger Alaskan 2 1/2 inch barrel "super snubby" in .454 Casull.
As always, "your mileage may vary".
