That load does sound excessive. I'd take better care of my Kimber than that.
Alliant recommends a maximum load of 6 grains of Unique, but that's pretty conservative at only 16,000 psi; SAAMI says you can go to 21,000.

I regularly load 6.5 grains of Unique with FMJ bullets and WLP primers for right at 905 fps. It throws the brass into the next zip code though. I wouldn't recommend you start at this load. Start at the 6 grains recommended by Alliant and work up watching for signs of pressure.
