I have shot all three calibers at one range outing. I was shooting them interchangeably using all factory loads with jacketed bullets out of my 8 3/8" barrel. The 460 load was Hornady, the 454 Magtech and I don't remember what the 45 Colt load was. I had no problems with them and they all fired perfectly.

As for recoil, the 45 Colt was like shooting a 38 Special. The 454 was like shooting a hot 44 Magnum with kick that pushed back into your hand. The 460 very loud and a lot of flame and the kick was more of a flip.

I don't know if this helps, but it might be a start.
