My shipment arrived last week and just wanted to let you know how pleased I am with my purchases. . Your copper solvent is the real deal too. Just amazing to put a drop on a bullet and watch it go to work instantly. No smell and no irritation if it gets on your skin, unbeatable combination. Thanks Jim and consider me a repeat customer.

I fired 50 Tubb's lapping bullets in a .223 today, cleaning after every (10) rounds. After using Butch's Bore Shine & a bronze brush, I wet a patch with KG 12 and stroked the bore (20) times as instructed. Then as a test, I wet the bore with Sweets and let is soak a bit. I did not get even a hint of blue!!! It appears to me the KG 12 really does work and work well.
