Rebel Hog - I have heard of some similar techniques in the past. I think one of them used GM Top Engine Lubricant. Many years ago, there was a break-in method that basically called for wet patch/dry patch; every shot for 50 rounds, that produced some very good shooting rifles. Be careful shooting a round through a barrel that has oil in it, though. Can really drive pressures up with full throttle loads.

All I know is that these premium rifle barrels are fairly expensive, and I want to do everything I can to make them shoot well. So I follow the manufacturer's recommendations on break-in. And they are suprisingly similar. I don't do the full break-in deal for a customer unless they request it and are willing to pay shop time, but I always put two or three rounds through a gun before delivery and clean between shots.

"Cleaning" usually consists of a wet patch of Shooter's Choice, ten strokes of a brass brush wet in Shooter's Choice (using a bore guide), and then however many wet patches it takes until they come out clean - usually only three or four with a good quality barrel. Finally a dry patch - fire again, repeat as needed . . .
