I'm not big on special barrel break-in procedures, either. I swab the barrel once before shooting, to clear out any residue from manufacturing. After that, I just take it to the range and shoot it. Usually I break it up into a few different range sessions, but that's due to time constraints - not any kind of barrel break-in schedule. I usually do swab the barrel between these sessions. With an AR, I use the first session to check for reliable function and get the optics dialed in, as best I can with a standard load. That's usually 20-40 rounds. Then next couple sessions, I'll shoot test loads that I've worked up. Depending on what I'm trying to do, those sessions can go anywhere from 20-100 rounds. If I find a load I really like, I'll finish up by getting the optics dialed in with that load. If I can get that done without shooting too many rounds, I probably won't clean it again, until accuracy starts to fall off. I make it a point not to go hunting with a clean bore. I feel like my first shot consistency is a lot better, if I have 5-10 rounds worth of fouling in the bore. That's just my method - you'll have to find one that works for you. I think barrel break-in procedure is mostly personal preference. I don't think it's necessary, but I also don't think swabbing the bore a few extra times is going to do any damage, either. I say just go out and shoot the thing and have fun.
