My dad had a gathering of fat rich guys at his farm about 8 years ago. They all brought their 22 revolvers. There were 5 guys with 5 guns they each shot them all and compared their 5 groups with all of the others. The worst shooting was a early 80's Colt Diamond back (dad's), the best by a small margin was a pre-war K-22 target. Close in second was the insurance salesman's, H&R top break target. I think this answers your questions. Ivan
