With the use of PbBlocker, I have cut my cleaning time by 90%

I treat my custom barrels with PbBlocker prior to shipping.

We fired 1000 hard cast bullets through a Glock 22 without cleaning and the amount of lead in the barrel was virtually undetectable.  PbBlocker was equally effective in hand gun barrels with conventional rifling.

I push a WW lead bullet to jacked speeds and did not coat my barrel with lead....it is GREAT!  I have treated all of my guns from my 1833 long rifle to my Enfield and Mosing Nagants, and also my 1858 Pietta Remington Revolver.
