Yes, exactly.
I'll put 50-70 shot through before cleaning again. I'll wait until the groups start to open back up a bit.
My rifle
Clean barrel=2 MOA
Fouled Barrel=.5-.75 MOA
I used to clean often. When I got the rifle it was just a two inch shooter. Not very happy. Then I had some scope problems and ended up firing 20 rounds at one. Boy was I suprised when the last ten grouped a lot closer than the first ten. I figured it was barrel break in. I cleaned it and put it away.
Next time I shot it, it was back out to 2" until I got a few round through it. Now I'll only clean her when she tells me to.
