Why do you call tungsten(WS2) danzac?
I get WS2 from Rose mill. Tumble bullets in a container with coated BBs, then sift them out and polish the bullet's on a shop towel.
After seating, I wax the exposed bullet area with a shop towel that was saturated with TurtleWax & dried. There may be a better wax, but I haven't had an issue yet. I do this because otherwise humidity/rain can turn the coating into mud in the field.
I pre-foul my barrels with WS2, and my first group is usually pretty good. To do this, I follow my cleaning with alcohol to dry out the bore. Then I push a dry bore mop through(a few times) that is normally stored in a solvent bottle full of WS2/BBs. I put my guns away clean, dry, and ready for use, -after every use. It's the only way to control carbon, which WS2 may contribute to, I don't know..
I'm experimenting with a barrel using only uncoated bullets, and watching with a borescope. A previous identical barrel gave me alot of use with WS2, and I had been watching it. I want to see that benefits of WS2 are actually free. But ya know, nothing is. So we'll see..
I've been using it for a long time, and have been happy with the results.
