Never did any bullets myself in moly. I hear and read that cleaning moly from a bore is quite the chore, however. I also hear and read that a lot of experienced shooters ONLY use moly coated bullets because the barrels last so much longer.
My thing is this: if you look at a fired/recovered moly coated bullet, you can see copper jacket showing clearly where the lands press into the jacket, and you can see copper stripes down the center of where the bearing surface contacts the grooves. SOOOO, if the benefits of moly are finished by the time the bullet is an inch or so into the barrel, what good is it? Does it make a difference all the way down the bore? I don't know.
I've considered using ONLY moly bullets in one of my 6.5x284 rifles just to compare it to another that will never see a moly coated bullet.
I'm also curious about Danzac coating and the black lubalox Winchester uses.
