I don't get it. Why would you need to clean and lube DURING the match?
I have a little experience with PPC, and intend to start shooting IDPA this summer, I have already reserved a time slot for my first match.
Is the round count so high that you lead up your barrel?
Anyhow, my standard procedure is to clean the gun the night before and then send one magazine downrange to foul the bore and make sure the load I am using is okay (it always is, but it is a confidence boost to see a nice tight group) and then I shoot the match. I feel as long as I have my gun well oiled, and am using quality ammunition, I don't have anything to worry about.
