I am at approximately 800 rounds in my 6mm creedmoor barrel. I have never cleaned it or put anything inside the barrel besides bullets. Group size has stayed consistent. The 6.5 creedmoor barrel i replaced had an estimated 500-600 rounds through it. Same experience.
That is my anecdotal experience. I have a tikka 223 enroute and will be much more strict on documentation of the exact number of rounds shot through it. I have zero plans to clean it. I see what happens.
