Hello Bernie, and welcome to Graybeard Outdoors
In my opinion the Raging Bull series doesnt suffer from the quality issues that plauge the other taurus lines. Having said that I would not advise you to purchase one unless you can handle it and go over it carefully.
As to the caliber choice, I would go with the 454, it is superior to the 480 in everything, with the exception of an insignifigant diameter disadvantage.
I personally dont find the recoil of the 454 to be over punishing, others do. I routinely shoot my 454's in quick double action with no problems. The ruger would most likely be a fine gun, but if you like a nice clean crisp trigger you will definately need to get a trigger job on the ruger.
