Just shooting it. I BELIEVE (being the magic word here) that breaking in a match barrel for anything besides bench rest is completely useless, unnecessary, and can hurt your barrel much easier than help it. It will get a good cleaning tonight, but the only time I'll clean it is when I start to see accuracy degrade. From my experience and what others are getting with the Mike Rock barrels (my .30-06 is a Rock) they go 400-500 rounds before they need to be cleaned.
Ritten,
You are right on the money with the break-in. I would however clean it a bit more often. I typically clean my match barrels after each match (88 rounds) for the first 3 or 4 matches. Then about every 200 or so rounds. That thing looks like it shoots pretty well. You need to get the brake off (probably need to re-sight it) and get over to Palo Alto for the F Class match.
