There is, in my opinion, no need for grease or lube of any sort
to prevent a chain fire if you have a properly fitting ball AND properly fitting caps. Period.
Lubrication is, again my opinion,
to reduce fouling buildup. It softens the fouling and prevents it from caking. It is well worth using, but it's value in preventing a chain fire is
secondary.
And the bit about fouling filling up the rifling in the bore and making the bullet unstable is, well, just stunning.
