I have the Smith 460 xvr 8 3/8" model. I run loads from 600-800 fps in 45lc and 460 mag loads from 1,000-1,917fps. I have never used factory ammo. Last trip out I hit a clay pigeon that was 50-75 yards out, on the first try. I used a 225 grain bullet flying around 1400 fps. It was my first time shooting that far with that gun. It is scary accurate compared to all the other pistols I have shot. I have not had to move the sights from the factory position for any of my loads.
Here is a video link of my hand loads (I wear foam ear plugs and 31db passive ear muffs for the hot and medium loads-hence I couldn't hear my brother's intro and didn't know he was already recording)

1st 45lc 200 grain bullet 766 fps average
2nd 460 270 SAA cast hollow point (my own cast)over 10.0 grains of trail boss around 900fps
3rd 200 grain jacketed "flying ashtray" over 38.0 grains of 5744 estimated at 1400 fps
4th 225 soft point jacketed over 38.0 5744
5th 240 Hornady XTP MAG over 45.0 grains of Win 296 for 1917 fps.
The recoil isn't bad, even on the hot load. It is a like a massage to the hands, compared to my grandfather's Ruger 44 mag single action with Winchester white box ammo. The concussion and noise are the reason I limit the number of full power loads I shoot. I probably have 700-1000 rounds through mine since I bought it in the first part of the year. I have only run 50 or so full power loads. My cast bullet knocks steel around like it is nothing. Clear a Texas star sometime with a 460
I shoot a 9mm modified XD for competition and then pull out the X-frame for some fun afterward.
I don't go to the range without the 460. I only use it for target shooting, but it is very fun and versatile. It is a work of art just as much as it is a beast and conversation starter. Yes, I feel like a super hero when I shoot it and it is fun to show off, but I still really enjoy shooting it even when I am by myself.
