hBN what size?

[High Binder]

Hey guys, I just ordered about ten pounds of hBN -5 not with the intention of it being used as a bullet lube but if this is the right size than I'm going to start lubing/loading with it as I won't make it though ten pounds for about a year and wont feel bad 'borrowing' some from it's real purpose.

So the question I have is: is -5 the right size for shooting purposes? Is everyone just applying via tumbler? Has anyone tried applying with a spray prior to chambering?

Re: hBN what size?

I am using the 7-k of a micron & the 5-k of micron size for Reloading & bullet Lube . I can not seem to tell the difference between the 2 sizes of Hexagonal shaped Nano particles for that task . Don't know if it's even humanly possible to tell differences when it comes to that extreme end of dry-lube size .
Any Nano size particle is Pretty Friggin Small though & I am ( really not sure if it matters ) when you get to that point on lubing friction inhibiting properties ? .
.
I just slow rotary-tumble in a jar with BB's & I think that is the best way, as you have to let it get beat into the micron pours of the Copper jacket for good effect . I think my Lapidary drum is doing @ least 40+ RPM on it turning .
Don't think just a superficial spaying or wiping of the hBN would really have any real benifits .

10 pounds will last 10 people a lifetime, wear a paint resperator, HbN is not good at all for the lungs

Ya that stuff floats around in the air in my reload bench area every time I handle the stuff . especially when I do a light buffing on the finished tumbled bullets before I cap-off the finished Rounds on loading . I know I feel it a little in my Contact Len's from handling it .

Nano size particles . Hard to Really Wrap your Mind around just how small that really is .
A buddy mailed me a pound of the hBN . It was wrapped/sealed in a plastic bag & then put in a plastic contained with a Lid . & then taped around the container it a few times . & then put in a USPS flat-rate sealed envelope & mailed down to me .
When I went down to my PO box & got it . There was white powder clearly on the outside of the package . Nano size particles . IT slowly crept, crawled and sifted and worked it way thew pours & seams, out all the container threw all the wrapping to the outside of the envelope . with just the vibration of postal travel across 2 states .
To this day I am surprised that I did not have the Postmaster General & the Feds. crawling up my ass & his from the white powder all over the outside of that usps package like someone doing a Anthrax scare .

Thank you for the feedback. For my purposes the size does matter but for shooting, I can't imagine that it would matter all that much but I figured I'd ask to be safe.

Spraying hBN held in solution via oil or alcohol, even water is a pretty good way of applying hBN to metal surfaces but you wouldn't get good adhesion, i.e. you could wipe it off with your finger. That being said though, you could simply spray it on and then load the bullet without touching it and/or spray it down the barrel but I'm wondering how effective that would be in preventing fouling.

Thanks for the tip on application, I'll do the can/BB mix but do you think it would work in a conventional vibratory tumbler (maybe running it for longer) as opposed to your drum?

I wish this would last that long. I'll be through my 10 lbs in about a year.

Do you shoot it and if so are you happy with the results vs. not running hBN?

Do you buff it with a paper towel or what? (sorry for all the questions I've never loaded with hBN before)

I'm half surprised the cops weren't at your house wondering about anthrax or cocaine. I once ate shit big time as I walked past a dept. at work where the dickhead running the area spilled glass bead blasting media all over the floor. The floor was slippery for months after that and I bet I watched 40 people fall on their asses in that spot over the following months.

Re: hBN what size?

By my math

I used 4 grains of HbN per 100 155 Scenars

7000 grains per pound/4 grains per 100 = 1750 batches

1750 x 100 bullets = 175000 bullets per pound

175000 bullets x 10 pounds = 1,750,000 bullets

1750000 / 365 days = you shooting 4800 rounds a day

I would like to shake your hand if you shoot 4800 rounds a day

Re: hBN what size?

I don't use it anymore, my time is better spent on other things versus coating bullets myself, and IMHO Tubb charges way too much, cleaning was a breeze, other than that I see no other benefits.

After doing a ton of research it looks like a lot of bench guys are applying it via alcohol/hBN soaked patching the barrel.

Looks that that is the low brain damage way of applying hBN vs. tumbling into the bullet. Anyhow, I've been developing loads for a new gun and as such I think I'll give this a go and see how it goes.

Thanks for the info guys.

Thats a round every 6 seconds from 9am thru to 5pm without a break in between!

Re: hBN what size?

The HbN is denatured alcohol is to burnish it in to the barrel, the BR boys do it to prevent first round flyers because there anal gun scrubbers
