Boron Nitride coating

If you stay up late at night and watch TV you will see all sorts of infomercials, miracle cures for baldness, miracle cures for erectile dysfunction and even miracle coated frying pans that wont stick. All these miracle products do one thing very well, they make the sellers wealthy.
You mentioned David Tubbs final finish system.............
Below is a custom made hand lapped barrel.
Below is a before and after fire lapped Savage button rifled barrel.
Below a closeup of a button rifled throat.
And the same barrel two inches from the muzzle.
Boron nitride is a high temp lubricant, how far down a standard button rifled barrel will Boron nitride last before these barrels are eating into the copper of the bullet. Another way to look at it is how good is your engine oil if you put sand in your crankcase.
For just 27 payments of $19.95 I will sell you some miracle whale snot bullet coating guaranteed to make your bullets slippery than a slimy slug sliding across a Teflon pan. (and P. T. Barnum said "There's a sucker born every minute.")
Even after fire lapping a standard factory barrel will never be a custom hand lapped barrel and miracle coated bullets wont change this.

This is why I clean stock factory barrels with foam bore cleaner, barrels like above eat bore brushes and the residue gives a false copper impression. Spare the rod and spoil the bore.
I've been playing with the hbn stuff a bit, is it worth the trouble, in most cases probably a no. Too hard to ever do a good technical and unquestionable analysis of any such thing, along with everything else gun related that nobody has a definite answer for 100yrs later.
Would it make a rifle more accurate, highly unlikely. Might it slightly lower fouling and reduce the frequency between cleanings, maybe, kinda my hope, certainly hasn't seemed to hurt it.
Effects on pressure, next to nobody has the proper equipment to measure that, I think it seems to but haven't done enough messing around with that aspect of it.
It was actually more talked about 5yrs ago and didn't really seem to catch on, potentially for good reasons, so its hardly the next gimmick, not that there's any shortage of such things...
Did notice a couple guys using it for pure copper turned bullets, might do more there, no idea, but probably doesn't hurt.
