The powder-coating works for bullet lube well. However be skeptical of it's aficionados that claim it increases bullet diameter to make a bullet fit. It ain't metal and flakes off promoting gas jetting if your bullets are small no matter how thick the coating is or how strong it claims to be. It is no cleaner and no better than 45:45:10 correctly applied. It is prettier in color than clear tack free 45:45:10 applied correctly. 45:45:10 also has no velocity or pressure limit either, your bullets do.
Also, if your bullets lead the bore, they don't fit, your alloy is wrong for the load level or your rough bore is abrading them, It ain't the lube when the bullets fit correctly..
I have tested 45:45:10 with ink verified fit bullets strong enough for the load and a polished bore to 2600fps in .223 Rem.. Zero lube failure but accuracy began to drop a little lower than that. If you get everything right you get a slight lube star on the muzzle starting at about 5-10 rounds and your firearm shoots clean with zero leading.
