Don't know if this would be of any use...
50+ years ago I was trying my hand at cast bullets. Managing to recover some fired slugs, I found that the back edge showed evidence of melting. Not wanting to get into gas checks, I cut paper disks to glue on the base. They seemed to help, but I was using epoxy (can't say why, other than being young and ignorant). It was messy and slow to cure.
Left that idea behind, but just today did some researching on the products of combustion of hot glue. The fire safety site I found named those products as carbon monoxide, carbon dioxide and some simple hydrocarbons.
Today I put a small lump of hot glue in a cheap stainless spoon and burned it. There was no visible residue.
As I said above, I don't know if this knowledge is of any use, but there it is.
The base of the bullet would have to be free of lube for the glue to stick.
