HBN Bullet Coating

[VenatusDominus]

Do y'all when lubing the barrel do it after every cleaning or how frequently?

Does anyone know of any toxicity that may come into play when using it in hunting rifle and the meat of the animal?

hBN is non-toxic unless you are using it in particle sizes small enough to enter the cell (don't recall the size off the top of my head). It is used extensively in cosmetic products. Like any fine powder, you to not want to inhale it.

When applying the alcohol slurry I wear nitrile gloves. I would recommend caution with regards to breathing the dust. It's not like you're gonna be in a cloud of it though. That's just common sense to me.

to the best of my knowledge David Tubb is THE MAN as far as hbn goes. He introduced the shooting world to hbn as a shooting product. Visit his site and read all he has to say about it, no one knows more about this than he does.

DO PAY ATTENTION to the particle size…I forget off the top of my head what micron size it's at but there's a point beyond which it doesn't serve as a lubricant nor does it impregnate the metal, just sits on top of it and has strong abrasive qualities.

I use this HBN on all my Benchrest bullets with I believe good results.Can up the powder charge .3-.5 . I never apply in barrel because we clean all the time 10-30 shots .
I am out of Tubb dust HBN . Cannot seem to find any up here in Canada.Would also like a larger quantity than the Tubb kit anybody on here have a lead to find it in Canada .Thanks

I'm. A fellow Canuck. Found my stuff on eBay honestly haha. 0.7 micron size, the brand was microlubrol. That was years ago, but it is often sold as a product for the manufacture of cosmetics, just look around for that as well and pay attention to the micron/particle size.

And I'd add this to my initial praise of this product: it's totally safe unless you inhale a bunch of dust (and inhaling fine particulate matter of any kind is bad) - they use it in women's cosmetics sometimes: not that a harmful product has never found it's way into cosmetics before BUT if it was aggressively toxic we most certainly would know.

David Tubb is whom I got the idea from.
Started using it in my custom 338-416 Rigby Improved 45° shoulder.
Velocities with uncoated and coated were vastly different, and the reason I tried it was because the solid brass bullets I was using were "sticky" in the bore. They weigh 323gr and are very long, but have exceptional BC.
I then moved on to all of my comp guns and was very, very satisfied with the results.
Have not tried it in any of my hunting rifles, however.

Cheers.

A good introduction to using HBN is a video on YouTube by "Long Range Only" (as I recall).
The guy explains what it is and what it does and how to apply it to bullets and bores.
One thing it does for target shooters and hunters is that no "fouling shots" are required as all shots go into the same group, first to last - IF you have the right rifle and load.

Yes! I forgot what video it was but that's one I used when I was getting started. Had to improvise a lot as I don't have half the things that guy (Jeff Broz) had in the vid, especially a rotary tumbler…but it's a great resource and should be considered required reading/viewing alongside the literature and instructions from David Tubb. Long Range Shooters of Utah also have a worthwhile read on their blog/site, more informal but good real world findings and reporting.

You can use any tumbling system. I just remove some of the corn media they let the small plastic jar go around . My experience is longer than I read on this site . Jm2c

hBN has a few potential advantages not yet mentioned. For one it's hydrophobic so it doesn't attract moisture. Another, and more interesting to me, is that it has an extremely high resistance to heat. I don't recall the numbers but it is impressive. It has been deduced that the coating can improve throat life. I'm not in a position to test the hypothesis but others may be???

 

[Dirtrax]

It has been put forward that many have reason to believe that Speer Gold Dot bullets are coated in hBN.
As for breaking in a barrel, I wait until the barrel speeds up. Sometimes the reduced friction/velocity is pretty close to getting things back to where I want.

No naked bullets! HBN is what I choose to apply to my bullets. Moly sulfide is probably slicker yet. The Lubaloy coating Winchester uses is maybe the best have I have tested. I shoot .17 Remington, .17 Fireball, .204 Ruger, .20 PPC and .20 BR at distant furry creatures. The coated bullets really extend the barrel life and the accuracy period between cleanings in the small stuff. I also nitrocarburize all of my barrels to extend the accuracy life.

I use pretreated steel bbs in a vibratory tumbler just loose with the bullets for anything 25 cal and under. No jar needed Ive found after much experimenting. Small bullets plate way easier. The heavy 30 cal pills I'll put in some kinda container and wrap that in a blanket with duct tape and throw it in the dryer haha. Works fine.

I always wash the bullets with soap and water first, then rinse thoroughly, before baking them in the oven around 200 or so (hotter for non tipped bullets) before the tumbling begins, careful not to touch them with my bare hands once they're cleaned
