560 rounds through my tikka ctr still going strong with no cleaning and no real break in, I cleaned when it was new, then after 20 rounds I did another clean and then stopped. The less you touch your barrel the more consistent and predictable your zero and cold bore shots are. I did see a slight loss in precision (maybe .4” to .6”) after about 300 rounds, but now never shoots over 2/3” (ten shot groups). But my goal is more for consistency than total precision. I think lots of shooters do load development with a freshly “broken in” clean barrel, then see accuracy drop off when the barrel starts to “foul”. I believe this is when you should start load development.
