[QUOTE="Master Carper, post: 3251114, member: 15527"] The accuracy of a barrel can be totally ruined by improper cleaning practices! I get in barrels all the time for recrowning, because of a "lip" at the muzzle, from letting a cleaning rod flop around as it exits the muzzle. I have guys tell me that their gun use to shoot under an inch at 100 yards, and is now shooting 3-4 groups on it's best day. I give the bore a proper cleaning and recrown the muzzle, and the next report I get back from a customer is that their barrel is now shooting under an inch again. Same goes for damage at the throat area, just in front of the chamber. Let a steel cleaning rod bang up against the rifling and it will destroy accuracy far faster than shooting it will. If a cleaning rod is used, it needs to be the proper size and preferably coated. If it is properly maintained, you don't have to worry about the throat or muzzle being abraded from the rod having a coat of "garbage" on it. Also, if cleaning from the breech end, a properly sized and fitted bore guide should ALWAYS be used! If cleaning from the muzzle, a proper muzzle guide should be used. In my 35 years of building custom rifles, I have seen many many guns accuracy totally ruined from an improper cleaning. Yes, there are a lot of guns out there that do not shoot well with a clean bore! This is especially true for .22 rifles. And since the vast majority of your older .22 barrels are made from a softer steel vs. that of a high powered rifle, special attention needs to made in their cleaning. A dirty .22 generally shoots better than a clean one, because the fouling build up allows for a tighter seal between bore and bullet. My .22 will shoot an inch or less at 100 yards from a bench, but it has to be dirty. If I clean it squeaky clean, it will shoot at best a 6" group at 100 yards. I can shoot a 50 round box of waxed lead bullets through it, take it to the range and it will shoot groups of an inch or less and do it for a thousand rounds. Clean it again, and it won't shoot worth a poot until after it has another 50 rounds shot through it. [/QUOTE]
