I have a pair of 480 Super RedHawks.
My Advice:
If you have a new set of unused 1" Ruger Rings with your new SRH call Ruger and trade them for 30mm. If yours have been used, just order a set of 30mm rings.
Next order a Black, 30mm UltraDot from

Next replace the grips with Hogue "Tamer" Grips they have the Smurf Blue Sorbothane strip down the inside of the back of the grips. They come standard on the SRH Alasken.
Last would be a Marbel Green Fiber Optic front sight for back up use.
Wolfe Springs ?? Probably not a real issue, as you will be shooting Single Action. Unless your trigger really needs improved, I would not change the springs.
Casting Bullets: The Lee 400 grain bullet works fine. The Lee 325 grain bullet looks great, but is too short, and is not real accurate.
I have been using AA#9 Powder for hunting loads.
For plinking loads around 10 grains of Unique should work fine.
In the 2011 Missouri deer season I filled my Antlerless ONLY Tag with a large Doe. I filled my Any Deer Tag with an 11 Point Buck.
I was using 355 grain Gas Check bullets.
Range was between 50 and 55 yards on both deer.
In my opinion the 480 Ruger is about as Bad as anyone needs for North American Big Game. With Full House ammo, the 480 recoils plenty hard for most mortals.
Good Luck
