PART II....just a follow-up to the first post on your break-in question. Sometimes with a new barrel you will find the manufacturer uses a pretty tough anti-rust treatment in the new bore. I find that most cleaning solvents won't touch it, without repeated applications of alcohol or solvent. so I recommend going to Wal-Mart and picking up a bottle or spray can of Brake Cleaner. That will clean that bore Lickity-Split!!! Just be very, very careful as that stuff smells to high heaven and will ruin the finish on most stocks and melt plastic as well. If you can, disassemble the gun barrel and clean it outside.
Good Luck,
Jim
