Re: FS Hexagonal boron nitride 70 nm
Same as David Tubb uses 70 nm MK-hBN-N70-Nano. 1 micron is 100 nano-microns. So, 70nm is about 1/2 the size of 1 micron, 1/4th the size of 0.5 microns.
Three grains per batch of 50 to 100 bullets works many people report. Place in sealed container with lead shot or BB's then tumble or vibrate.
Many guys have used this for years and report it is better than moly in reducing barrel heat, longer barrel life, improved accuracy, ease of application same as moly, and no toxic risk potential.
Have bought HbN from retailers such as in Canada.
Using the Imperial measurement it was short on wt. Troy pound is 13. something ounces. Also was short on quality. HbN naturally absorbs moisture from the air and if it has done so then your not getting pure HbN.
Now I buy from the manufacturer and can tell the difference. So, for sale is pure 70nm HbN 250 grains bags enough for 8,000 bullets $20 shipped conus.
