I own and have owned over a dozen Kimber's in my life time. Not a single probem yet with any of them. My current Kimber LongMaster Classic in 223 will throw Black Hills Red Box 50 grain V-Max in groups under an inch with no problem. And better with handloads.
This has become an age of the internet. And one or two bad stories go 1,000 times farther than the same amount of good stories. Do not believe most of what you read. Some maybe, but not most.
Do not take this personally. But your thread is perpetuating that Kimber's had a dismal period of accuracy in their history. And you openly admit you have no experience with them. But you believe the older ones are inaccurate?? Why?? Tom.
