Here's how to make a foul-out. This one uses a power supply. I also have a scan of how to do it with batteries. If your barrel is really leaded, it will take a lot of batteries. Drop me an e-mail and I'll send it. t_cbeck(at)att(dot)net
Lead Remover - Parts and Equipment
Small DC Power Supply that goes from 0 to about 12V and has a meter to read current (milliamps)
¼” diameter (approximately) steel rod, longer than your barrel. Alloy isn’t important
4 feet or so of 2 conductor lamp wire
2 alligator clips
Rubber cork that seals up the barrel end
Some ¼” O Rings to go around the rod (usually available from a HW or car parts store)
Electrolyte: 25% White Vinegar, 25% Ammonia, 50% distilled water
Place a few o-rings on the rod to prevent it from shorting to the barrel. These should be smaller than the bore diameter to allow electrolyte to circulate and gas to vent out.
Plug the bottom of the barrel with the rubber cork
Drop the rod down the barrel
Fill the barrel with electrolyte to within about ½ inch of the top.
Connect the –V output of the power supply to rod and the +V output to the barrel or receiver.
Turn on the power supply and adjust the output current to something between ¼ and ½ amp (250 to 500 mA). Voltage is not important, but if you can’t get the current up over 100 mA without going over 12V, your barrel is pretty clean to start with.
The barrel will bubble quite vigorously if it's really fouled. If you filled the barrel to the top with electrolyte it will overflow and make a mess. It's not a bad idea to wrap a rag around the outside of the muzzle and secure it with a couple rubber bands.
As the lead comes out, the current will fall off. Once it’s down to 50 mA or so take everything apart and clean the barrel normally. If it’s still leaded, clean it with an alcohol patch and brass brush, clean the sludge off the rod, then repeat the electrolysis.
I once did a Whitney Kennedy that produced enough lead to make a 22 cal. bullet. It took about 4 clean and repeat cycles over a week. Once done, it shot great!
