HWD I explained this process but I don't remmember under what topic,but it's easy.You need a good rifle vise like the tipton or some one to hold the rifle still.I use a tipton cleaning rod,I clean the rifle real good,this is the only time I use a bronse bore brush,after this I only use nylon bristle brushes.If you could use a boroscope to look down the barrell you would see why cleaning can be difficult.My remingtons and rugers looked like crators in the grooves of the barrel,and thats why cleaning them is so time consuming.I use valve grinding compound,since I was a mechanic for 33 years I have course,med,fine.I also bought a lapping kit from midwayusa.com you can get a good bore lapping kit from brownells.com also.After a good cleaning I use a nylon brush under size and wrap a cleaning pad around,I've also used a metal slotted tip and cleaning pad and I put course valve lapping compound all over the end that goes into the barrel,you want a tight fit but not so tight that the rod binds up and has to be removed,on a bolt action I use a bolt cleaning guide and it centers the compound,push down and back 75 times,during that time I remove the rod several times to put new lapping compound on,down and back is 1 stroke,I repeat this with med,fine,I use the midway lapping compounds next,I start with course and work my way to fine,I clean between each compound and when finished I put flitz(polishing compound) on my rod and stroke 25 times.Clean the gun well remove all grit.Then the test comes,push a cotten ball down the bore and look down the barrell with a bore light and see if you have any rough spots,the cotton will stick to rough spots,if no cotten is seen lube the barrel and you are done.Every weatherby,sako and many others as well as custom guns have this done before it leaves the factory.It in theory creates accuracy,and the only guns I've shot and then lapped the barrels,the accuracy was a little better,but the reason I do this is to cut down on cleaning time.There is no rough spots to hold copper or carbon fouling.I even lapp my pistols.I own 1 weatherby but its nice to know I have as slick a barrell as any custom gun out there.Drop-Shot
