Somewhere I have a book that explains the exact process that you are describing...and as soon as I find it I'll post the source. This method that you have presented is the TRUE Lapping of a barrel.coyotejoe said:Agreed, what most people call "lapping" with grit on a patched ball, is enough to take the burrs and sharp edges off the lands and that may be all that is needed. However, I have often found loose and tight spots along the length of the bore and those need to be evened out by actual lapping with a cast slug, some fairly aggressive grinding compound and a lot of work. If done properly, lapping can even produce a choked bore which is quite beneficial to accuracy. I have made myself a special lapping rod with a large two handed T handle using a bicycle front wheel hub for ball bearings of rod to handle. It takes a lot of time and effort to enlarge a rifle bore by .001".
I quite agree...I will lap a barrel as a last resort.coyotejoe said:Well yeah, if it ain't broke don't fix it but most barrels will benifit from lapping.
Have you tried this product?? I'd like to hear more about it.. 8)bigblock455 said:Wheeler sells this lapping compound that you rub onto your bullets and fire lap it,
