[QUOTE="WildRose, post: 557039, member: 30902"] IF you have already gone through the manufacturers recommended break in process and are still seeing a lot of copper fouling relative to the amount of rounds you've put down the tube lapping may well help you. One problem with fire lapping is that it isn't even. Most of the abraision is within the first third of the barrel and little to none in the last third. If it needs lapping I'd suggest hand lapping instead. All you need is a tight fitting arbor, a good one piece brass or fiber cleaning rod, some patches and some patience. I keep some Brownell's 800gr silicon carbide lapping compound around and it would be a good one to use. Just put some on a patch and from the breech end work the full length of the barrel about ten rounds (back and forth=1 round). Then blow it out with some carburetor cleaner, and run a couple of dry patches through. Do this after a good cleaning, and then go shoot a few rounds, clean and check your copper fouling. Repeat up to four times and it should give you great results. Not as easy as fire lapping, but it should be both more controlled and more effective and certainly a heck of a lot cheaper. Make sure you are cleaning with a good copper and carbon remover like Gunslick's foaming bore cleaner or Wipe Out. Whether you do it by hand or by fire lapping you definitely want to be careful not to over do it. Remember by it's very nature lapping is removing steel from your barrel, thus shortening barrel life.
