errolhunter,hi there,I learned about hand lapping a barrel from a gunsmith down south.I noticed that my weatherby was super easy to clean and my ruger took an hour to clean,my gunsmith took a boroscope and showed me why.The barrel groves looked like crators in the ruger and remingtons,but the weatherbys were smooth.You put bore lapping compound on a brush wrapped with a cleaning patch,I think I used 357 brush cause you don't want to put too much pressure on the bore,push the patch on a cleaning wand(I use tippton)down the bore back and forth with lapping compound on it,I stroked down and back,50 times with course,75 times with medieum,and 100 strokes with fine,cleaning inbetween each compound.I clean up and use flitz polishing compound a few times and clean well.Run plenty of good lubricant on patches and keep it oiled or it will rust,but the bore will be shinny and slick.Easy to clean from that point onward,and when I used the boroscope after that,the crators were gone and my remington and ruger clean super fast and I'm told it helps with accuracy but the shooter has to do his part.I hope I made it easy to understand,If not ask me to do it again.I'm told that is one of the reasons weatherbys cost more than my ruger did.drop me a line if I can help.Drop-Shot
