I know a fellow that was on the team and he is one of the most anal people I know when it comes to cleaning his rifle.
I know several BR competitors and they all clean there rifles between strings. At a BR match there is always two things going on.... People loading ammo trying to match conditions, and competitors cleaning their rifles.
I once knew this girl in high school who got a hotdog stuck in her... ah nevermind, I'm notsure if it actually happened because I wasn't there to witness it.
