SkyDaver, jfruser,
Yes!! The standard Outers Foul Out was designed and built with such a low-power, power supply that any numb-skull could leave it on overnight and not have to worry about the barrel...... it works "ok" but it does take way too long.....
Here is what you can do to make the system much better........
1) Get the chemicals from Outers (for copper and/or lead)
2) get a .125" to .20" stainless steel solid rod (about 2" longer than the barrel you want to use it in).
3) some rubber grommets with the ID slightly smaller than the shaft you have
4) rubber stoppers to act as a plug at the breach end.
5) electrical aligator clips and some wire.
6) get a 9V battery and hook the positive to the frame of the firearm and the negative to the stainless rod.
When you hook it up, it works very fast. After about 15 seconds, pull the rod out, wipe it off and reinsert. After 30 seconds clean the rod again, and change the fluid.....Repeat maybe one or two times max.....
You will have a super-clean barrel....
I too have cut the standard power supply out of the loop and use a 9V battery. It usually works in less than 60 seconds per treatment. I put a Fluke 789 milliAmp meter in series to see when the current drops off. This is how to tell that either all the fouling is removed, or the rod and/or fluid needs to be changed.
I am through scrubbing
More barrels are ruined by overzealous cleaning than anything else....
My $0.02.....
