I took my USP to the range and ran 200 rounds of the dirtiest range ammo available through it. I came home and stripped the weapon, put it in the tank and ran it for 8 minutes.
I pulled the barrel out and ran a patch through the barrel and it came out with only the most minimum of traces of fouling on it. I rinsed all the parts with hot water, as instructed, then ran them through the oil bath. When I pulled the barrel from the oil bath, I put the bore scope on it and it looked perfectly clean.
The lands and grooves were all crisp and clean, with a thin coating of oil, the chamber and feed ramp were basically spotless. I now run all my parts through on a 12 minute clean and an 8 to 10 minute oil bath. I reassemble with a clean, white rag and surgical gloves before returning the weapons to their respective case.
In almost 2 years I haven't had any issues and the all the weapons are still in pristine condition.
All in all, I really like the unit and would like to get a larger, carbine sized one for the reloading bench, if I ever get around to getting it all set up - but I still have a yard to get growing, a kitchen floor to replace and about a dozen other things on the home improvement list before I get to set up the weapons/reloading room.
