How much time between the 30 rounds? All in the same session, or over a number of trips?
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?
