Has anyone tried Wipe Out on barrels that have had Moly coated bullets
through them followed by normal copper jacketed projectiles ?

Also, any feedback how Wipe Out works on barrels after the firing of
pure lead bullets ?

Wipe Out won't be much more effective on lead than a standard bore solvent. When I talked to the inventor of Wipeout last summer, he said he had a lead specific version formulated, but it kept dissolving the lead seal on the bottom of the cans.

I can't imagine that Wipe Out would be very effective on moly. When that stuff gets built up, I go after it with some JB compound.
