Go shoot the thing. IMO the break in procedures are a bunch of hype. On super accurate premium match barrels, they are usually hand lapped anyway. I used to go with the long drawn out affairs of barrel break in back in my high power days. I soon found out it doesn't make one bit of difference. A accurate barrel will be accurate. One that is not might be able to be saved by smoothing out machining marks ect. But that is a whole different story.
Go shoot the heck out of it. When you get done clean the thing and be done with it. 99% of shooters will never see any difference no matter what you do with it.
