................The Lyman spray would have no negative effect on the lands engraving the paper, and hense being blown to tatters as it exits the muzzle. The beauty of the stuff (or similar) is that once the carrier evaporates it leaves the dry lube behind. Being dry it has zero tendancy to have crud stick to it.
The only negative I can see to it is the fact that no one can see the dazzeling white paper patch, and oooh and aaah over it. Generally the stuff is a dull gray so the patch and exposed lead just haze together
