I don't clean my barrels very often anymore. I do the "normal" break-in with 20 rounds (cleaning after every shot for 5, then after every 2 for 10, then after the last 5). After that, I typically shoot 200-300 rounds between cleaning. Honestly, my barrels seem to shoot better when they are good and dirty.

Have you tried going 100+ rounds without cleaning to see what you get?
This is usually a couple range sessions. I make sure to let the barrel cool down between 3-shot groups. I did do the proper break in schedule also. I really noticed it on a Savage predator 22-250. Will shoot very tight .3-.5 groups then around 35 are so shots after a couple range sessions group opened up around a inch. Once I gave it a good clean it right back to .3 groups. Thanks for the info!
