As bob said could be stock issues also but if it took 3 hours to get the barrel clean it must have had some serious copper build up!
This is all new to me. I never owned a centrefire until I moved to NZ. What method / material to do this?
I'll have to find time on a range to do that. Bit hard on a public day when everyone is chomping at the bit for their time to shoot.
Get some autosol and give it a good scrub now its free of copper
Will clean up quick once its lapped
forgot to say I did that on Sat. Looking good.
