[QUOTE="VinceMule, post: 2551159, member: 122164"] Best to buy a barrel blank and have it set to be put on, This kind of thing is very, very irregular. Barrels that take 30 rounds to get to a point where they start shooting well, first need to be cleaned down to the bare metal, then bore scoped, then determine the bore dia at the muzzle, breach, and points in between. All the top barrel makers would agree to replace the barrel if it was one of their own. Barrels that need a lot of rounds to get back accuracy, can and Will become unpredictable in terms of accuracy. Never think that keeping your barrel clean is a bad thing. Fouling is not a constant, as the layers of Copper, then carbon keep getting thicker, reducing the bore dia. At some point, the carbon becomes as hard as the steel. I have seen barrels that had so much fouling in them, that a Minimum book load produced so much pressure, it was hard to get the bolt open. Bore scoping that Sig, would surely be an eye-opener. Another issue is that accuracy will be lost due to fouling, then removing the fouling by a gunsmith will be so time-consuming for him(specialized equipment) but it will be more cost-effective to replace the barrel. Most gunsmiths have little to no patience with guys that don't want to clean their guns, then want their guns cleaned for cheap money when Shop time is usually $60-120 per hour. Most gunsmiths know the problems on neglected barrels and just will tell a guy that they do not have the time to do the job properly. ON std hunting rifles, gunsmiths make a lot of money cleaning and sighting in rifles for the owner. The Quality of the cleaning job is in question, because on neglected barrels, a guy could be looking at 6 or more hours of work, not to mention the supplies used. At some point of neglect, barrels can not be cleaned, the carbon is as hard as diamonds. [/QUOTE]
