A couple of things have surprised me. I had believed that cleaning the can would be the most important thing. Nope, cleaning the gun is more important. The chamber and extractors dirty up quickly especially in the pistol. I have a cheap TX22 pistol and a CMMG dedicated AR upper. There is only 1 brand of sub sonic ammo that operates the actions most of the time. Winchester .sub sonic 22LR will run 150 rounds through the AR before failing to eject. The pistol will dirty up after 10-12 rounds.

It is still fun to shoot these guns. I switch the can back and forth. I want to buy another can but my wallet says 'not yet.'
