Hexagonal Boron Nitrate Powder

[JSilva]

I'm looking around for other options for lubricating bullets besides the usual suspects.
I like tumble lubing, but I hate the tacky mess and the two day cure associated with that whole mess.
I was wondering if anyone here has any experience with HBN powder and leaf bullets. I've got s pound of this stuff on the bench. I think I'll tumble a little bit on a sample and load like usual.
Any thoughts are appreciated.

In all honesty, it's on my list of things to do. My plan is to mix it with 2 part epoxy paint for use as a cast bullet coating. It also has great potential with jacketed bullets, and seems to go into solution with 90%+ alcohol readily for use as a jacketed bullet coating, and also as a bore coating. David Tubb likes it, and that's enough to get me to at least try it. The stuff is expensive though, around $100.00/lb in the grain size I want to try.

I tumble ALL my rifle bullets in it now. Have for a few years. I love the stuff. I may HBN tumble my very first cast bullets I cast last Saturday. I've been wondering about it as a boolit lube. It is great stuff on mono metal and jacketed rifle bullets.

Can you tell us uninformed about your tumbling method and what micron you are using?

[coldtriggerfinger]

I don't remember which micron the powder I use is. But , it wasn't very expensive. I use a Harbor Freight dual drum rotary rock polisher.
I wash the bullets in Acetone. Just pour half a cup in a pint jar . Pour in a box of bullets and swirl it around good. Pour off the acetone . Then pour the bullets onto paper towels. Dry them off good and pour them into the half pint canning jars.
Put 1/8th teaspoon of HBN powder on top of the bullets. Put the lids on Tight . put the jars in the tumbler/polisher drums. One jar goes in upright . one upside down. ( so the rotary action doesn't unscrew the lid.) Put the drums on the machine and turn it on.
Let it run for 1 and 1/2 hours.
Open the drums pour each jar of bullets into a doubled cotton tube socks slinky them back and forth for a while. Pour into another cotton tube sock. Slinky then some more .Then pour the coated bullets back into their respective boxes.
I can do 75, 6.5 bullets per jar or 50, 375 bullets per jar.
Then load and shoot. I haven't tried. 416, 458, or 475 bullets yet But plan to.
No doubt there are more a retentive ways to do it. Just not sure they benefit over my way . Which was taught to me by the guy that got me set up with HBN.


( next day) I think I got this post edited so it's more understandable.
Stupid word replacement on this fon.

I've done around 1500 bullets so far and have not used 2 heaping table spoons of powder.
I much prefer it to moly tumbling.
The cold bore shot is ALWAYS inside the group. Bore stays clean. Barrel doesn't heat up much . It doesn't rub off like moly does. There is a great thread on HBN tumbled bullets over on Long Range Hunting forum.

There are other threads on HBN there also . This thread explains it far better than I can as far as rifle bullets and barrels go.
