I almost bought one back in the mid-1980's when the SuperAmerica was running about $700 or there abouts. Then I bought a Remington 541S and it shot so good, I didn't consider buying a kimber since. No experience with the rifles. Frankly you can get the same accuracy with a lesser priced 22 rifle. For example, my Weatherby Mark XXII is an excellent shooter and consistantly groups under an inch at 100 yards. As you can see, I do like the Yuppie 22 rifles.
I know this is not the answer you are looking for. The Kimber's are beautiful rifles!
