Does coating inside of barrrel with Melonite increase muzzle velocity?

Melonite: a pistol builder told me that if I have the barrel coated with melonite, that it would increase muzzle velocity of a 1911 45 ACP by 20%, and the same for an AR-15 in .223. I'd be surprised if it's that much, and yes, he meant 20% for a velocity increase. So my question is this: "Does coating the inside of the barrels of those guns with melonite increase the muzzle velocity, and if so, how much, either in fps or percentage?

20% velocity increase = 44% increase in energy. This gunsmith's claim is that now all that energy is being lost to friction in the barrel? And that professional shooters, the US military and gun manufacturers don't know this?

Just for fun, ask him to set up his chronograph and prove it.
