Hi - I did this test last summer and thought I'd put the data here (and other forums). Using my B22FV outdoors with a Caldwell Chrony I tested a few brands. Around 30*C and light wind in my face. Note the ES of CCIs as about the same as SK+ & SK-FlatNose for about half the cost. ( ERR = NO Reading) And my rifle only has 2-3K rounds thru it.
