HBN prices

[Baddog0302]

I've been pondering coating bullets for my new barrels {22BR & 6 BR}. These are the prices I got from TAI Lub. in case anyone else is interested.

AC6111 - Bore treatment - 1/2 oz. jar: $36.95

HCPL - Bullet treatment - 1 oz. jar: $36.95

Their site, under HBN lists 1Lb. and costs, they also have a link saying SAMPLES, click on that and you get a 1 # of the grade you click on added to your "cart" W.A.F.W.O.T
PLUS they are located in Canada , that has got to cost $$
In all fairness and searching for the lowest $$ I have asked for prices shipped to the US,
" we shall see"

I purchased some HBN a while back to try instead of using my normal moly coating. But I came a pone some articles on this web site that were disusing some problems with the product. There were pics showing inside neck cases with scratches from pulled bullets that had be coated with HBN. Has anyone seen this or know the reason for the scratches?

Also what is the biggest atvantage of HBN over Moly? Thanks

Thanks Badddog,
I like this quote from that page.
The difference in lubrication you mention is so small, we humans would never know it exists. hBN will clean up faster, is cleaner to work with, withstands moisture (something moly and WS2 won't), and is not a health hazard as are the other two. hBN is also more heat tolerant.

Still trying to make up my mind to switch to HBN.

I switched to hBN 8-10 years ago from moly. Haven't looked back!
I bought 1 lb of 70nm hBN for about $110 and packaged it up in 1 oz bottles and sold enough to pay for the hBN and supplied myself and my Australian friend. Folks were still wanting more hBN so I bought another lb and made up more 1 oz bottles.
Bottom line, at no net cost to us we have STILL more hBN to use for our bullets!

An added note, I sold the 1oz of hbn for $17! A far cry to the $36 for 1/2 oz of "barrel conditioner!!
I have been coating 6mm bullets for 10 yrs now (I tried un-coated in my 7mm and stayed there as it shot so well!) and I believe I have used maybe 1.5oz of 70nm hBN in that time for impacting bullets in a vibrator as well as making a slurry
with 92% alcohol for coating the barrel after cleaning. I shoot about 2500 rounds a year in this gun for 25000 rounds processed! Now I used a patch moistened with EEZEEOIL gun lube with about 1/2 medium straight slot screw driver blade full sprinkled onto the patch and keep the patch in a poly bag and re-use it each time I clean the barrel.

If this missive sounds like a recommendation to get with a couple shooting buddies and going together to buy a whole lb of 70nm hBN and not pay the rip off prices at the beginning of this thread,,, you just may be right!

Started messing with hBN after hearing how D. Tubb’d switched to it and offering his bullet-coating service as a product to other shooters.

Yes it has benefits over WS2 or Moly, and back then that outfit up North was selling a pound of 0.5 micron for ~ $70 I think.

I don’t ‘roll my own’ anymore; still have ~ 1/3 lb. left after using some, selling oz’s to others for ~ $10/ea., shipped.

$36.95 / oz. seems like a lot but then I wasn’t looking to make money, just recoup my cost + a bit for my time & effort to package & postage.

I recently started using HBN, having used moly in the past.

While looking for sources to buy HBN, I ran across several sellers that posted cautions about the 70 nM sized particles, saying that particles that small can penetrate the skin directly.

I read the MSDS, here is a link, https://www.lowerfriction.com/pdf/12.pdf. HBN seems to be quite benign, in fact 10 micron sized HBN is used in cosmetics but I'm not comfortable with the idea that it passes directly through the skin.

Also, this site http://sandblastingabrasives.com/hexagonal-boron-nitride-powder-order-page-781.html recommends larger sized particles for coating bullets and barrels.

• Bullet Coatings (Dry Lubricant used in a vibratory tumbler, order the -5 micron)
• Gun Barrel Coating (Reduces Friction, dissipates heat, may extend life of barrel. Order the -5 or -10 micron)

-5 micron means that most of the particles are less than 5 microns in size. -10 means that most of the particles are less than 10 microns in size.

I was having a hard time finding -5 size in small quantities so I ordered 2.5 micron. That means that the average particle is 2.5 microns in size, somewhat similar the description of -5 micron.

-5 micron (< 5) means that most of the particles are less than 5 microns in size. -10 (< 10) means that most of the particles are less than 10 microns in size.

Agreed that smaller in this instance may NOT be better, when viewed from a personal safety standpoint.

Particles of any substance this small pose an inhalation risk, entirely different from risks associated from skin absorption.

As an aside, bear in mind that 1.0 micron = 1,000 nanometers.

I trust that for our purposes the really fine stuff @ 70 nM is neither appropriate nor cost-effective and may well present an avoidable health hazard at the same time.
