I had one in 280 AI, since sold.
Cons
1. feeding was annoyingly unpredictable. 2. Had to polish feed ramp, gouged brass off the shelf due to a burr.
3. Recoil was punishing without brake.
4. Would not shoot heavy bullets over 140 grains at all.
5. Barrel got hot, fast!!
Pros
1. Light!
2. Love the kimber safety and blind mag for bad weather
3. Great trigger, pretty easy to adjust too.
4. Action cycles smoothly, I think the sharp shoulder of the AI was what gave me feeding issues, so that might be more of a cartridge con than a ding on the rifle.
I sold it to fund my first custom built on a Pierce TI action in 6.5 PRC. No regrets
