hBN users, barrel slurry?

[schumi]

I see people post that they are using a slurry in their barrels to prep them. But what is the ratio of powder to alcohol?

 

[mshelton]

Mine is around 30 to one, probably could go closer to 50 to one.

 

[schumi]

Of all liquids to use, why would you use alcohol?
Alcohol, happens to remove the boron better than anything else. I removed the boron from a batch (500 pieces) of .264 bullets using an alcohol bath. Couldn't tell they were ever coated Alcohol breaks down the boron very quickly 8)

I've read that the alcohol is used in a slurry to prep the barrel after cleaning because it evaporates very quickly and then leaves the hBN coated inside the barrel.

Is there another liquid carrier that you would recommend to mix with hBN? I'm getting ready to try this and would like some recommendations.

Thanks, Jerry

isopropyl alcohol evaporates fairly quickly leaving the hBN residue behind in the barrel. I doubt it breaks hBN down.The residue seems slippery after the alcohol evaporates.

 

[Hopkins]

It doesn't break it down.

high content alcohol IS THE METHOD for applying a prep to the bbl inspite of comments to the contrary.
the detailed method is an article on this site, as is the bullet coating method.


it settles out fast so make sure you shake it well prior to use...and it is a different size than the hbn used on the bullets.

googled away and it doesn't seem to be soluble in any alcohol. As I said, isopropyl alcohol won't break it down. Part of the bullet coating protocol involves impacting the bullets with steel shot or other media in a hBN rich environment. The process is to impact plate the bullet surface with the hBN. If merely dusting the bullets with hBN would suffice, that step could be skipped. If the bullets can be washed clean of the hBN with alcohol they obviously haven't been plated. Of course you could wash them clean with acetone or any other solvent. Whether or not swabbing a barrel with a slurry of hBN adds any value to the treated bullet protocol is an open question. hBN is a pretty stable form of Boron Nitride. If you search under chemical stability of Boron Nitrides you will find a list of examples of true Boron Nitride solvents.

Will alcohol help if I want to impact-wax my car? Or will it "break down the boron"?

 

[Syncrowave]

Boron nitride is a very, very chemically stable compound. If you think alcohol is going to "break it down" – or dissolve it – I've got news for ya. It's about like saying that dish detergent will dissolve Teflon.

If you want to dissolve hBN, you're going to need something more like hydrofluoric acid, which also eats through glass.

By the way, boron is different than boron nitride. Boron is an element. Boron nitride is a compound of boron and nitrogen.

It's simply a much easier way of saying hBN. But I really wouldn't expect you to understand that either. Trying to be helpful here is a complete waste of time.

i'm not embarrassed by their slow, old, poor methods.
the world record holder, jackie s, and i chamber the same way.....not like the guys you follow.
i shoot hbn, do you ??
maybe you should take your own advice.

Hey stool, aka mike in co. Wasn't the embarrassment you received from G. Ulrich & Mr. Kelbly on BRC enough? It really is about time you take the advice you have been given over a number of years, on many sites, to "shut up, listen and learn".

Thanks for the help. What ratio are you using?

Mike in co-aka stool. You have bragged for years, yet NO one has ever seen you shooting, much less performing barrel chambering. As for the hBN, i'm sure the good RG Robinett would gladly tell you how many years I used and also sold it. I had mine formulated before David Tubb started using it. Don't compare yourself to Jackie Schmidt. You aren't in the same league. He was also one the old timers on BRC that couldn't stand you and the BS you spread on a daily basis. I'm surprised Wilbur hasn't figured out who you are, and again banned you from the BRC site. Donovan Moran and I quickly figured that one out ;D

 

[mshelton]

Exactly Syncrowave,


Still haven't heard any other ratios, which I think was the original question.

 

[stool]

just becasue YOU have not shot with me means nothing in the real world.
i posted for years , clearly stating i shoot mostly club.
i shot 1000yd last year at crc....ist in score lite gun 3rd match. next match was state championship, i finished 4 in score...MY 4TH MATCH.
randy likes me, and was quite pleased when i shot my 0.116 308 win group with AN AR10 with his bullets.
jackie and i talk, we have some similar background(marine machinist)....i never said i was in his league..i did say i used his chambering method.
g.david tubb and i disscussed 6.5x47 before you were out of diapers.
throw all the names around you want...i have been around for a while with no plans to leave.

if you sell hbn, one would think you would spend some time learning the facts, which you seem to be missing.
i noticed you said, sell hbn, not USE hbn. so just making money with no investment in the product ??

hbn goes a long ways...i use slightly more hbn with shot than moly...so just a bit on the end of a popsicle stick and let it run. then add bullets and a bit more.

Ummm..... yeah. I don't know what to make of all this....

 

[Hopkins]

I prepare my slurry by color. I add enough hBN to get a milky colored suspension in a freshly shaken container of isopropyl alcohol(IPA). I don't think you want it caked in your barrel just a light frosting. I'm only treating the barrel after cleaning. I have my doubts about how necessary or useful doing it is. The proper coating of the bullets seems more important. I do know that properly coated bullets will have a consistent velocity drop compared to untreated bullets of 30 to 50 fps in the loads I use.

Thanks very much. This is what I was looking for.

Schumi,

I recently bought a "kit" for making a barrel slurry, it calls for 1 teaspoon of HBN per 16 oz of alcohol. It does say to use 99% pure isopropyl alcohol for the slurry.

I have only pushed HBN through a barrel one time, so I don't have the experience to tell you whether that concentration is correct.
