Danzac & Barrel Cleaning

[Kabang]

I've been cleaning my F-Class .223 very well between matches and at the beginning of a match I shoot 5 foulers and 4 or 5 sighters before the 15 or 20 shot string. Last weekend, in my 1st match, the point of impact moved around quite a bit in virtually zero wind at 300yrds and I scored a 144-4x, the next match I scored a 198-6x,which would be pretty good for me. In the last match with winds a little more evident, I scored a 199-8x which was really good for me and the rifle was shooting really good, but probably where the rifle should have been shooting all along. I have no idea why the rifle shot poorly in the 1st match. I'm wondering if the coating has anything to do with this relative to effective fouling?

I've have noticed my .243 takes several rounds to settle in when using WS2/Danzac. A while ago others found that when using Lock-ease to treat the barrel after cleaning the first shots are closer to the impact point. I found that it worked well with moly too. I've run out and haven't found anymore lock-ease so can't say how it works with Danzac.

The idea is, that as you fire the gun, carbon from the powder burn and moly/danzac/boron nitride lubricant coats the barrel. By spraying a light evaporative oil with graphite and the bullet lube of choice you precoat the barrel and make it get it to settle in faster.

I've tried making my own. Alcohol doesn't work well. I believe it does not carry the graphite & danzac well. Kroil coats the barrel well but doesn't evaporate and has to be wiped out taking some of the powder too. I'm looking at safety solvent, mineral spirits, or lighter fluid as a carrier. Need something that will creep like penetration oil and carry the powders into the pores.

CPorter,

Just bought several bottles of Lock Ease. It is a stock item at NAPA stores.

General Electric has listed under their Advance Materials section:
Boron Nitride Spray II- High temp. release coating. The can lists:
Butane
Acetone
Propane
Ethanol
Boron Nitride
Organic clay
I have used the Lock ease, which is easy to use but then when I switched to BN I also switched to the BN spray. Just spray a patch punch the bore & your done.

wc872,
I went to the GE website but was unable to find the BN spray you referenced to.
Do you have a link or a supplier you could give us.
Thanks,
Wayne aka WAMBO

McMaster/Carr has it. In their search box you can type Boron Nitride which will generate a list or punch in: 10515K35 which should be a 13 oz. can. While expensive one can will last a lifetime. It comes out as a white powder when sprayed.

Hello Everyone,
This website http://www.cdvkiln.com/menufusingsupplies.htm also has the Boron Nitride spray from G.E. It costs about $40.00 plus shipping.

I've tried making my own. Alcohol doesn't work well. I believe it does not carry the graphite & danzac well.

I use 91% Isopropyl Alcohol with Danzac and the results are excellent.

How are you mixing it? I mix it to a light paste consistency. I get a good coating on the bore and 100% evaporation of the carrier,alcohol).

If and when using the hBN, the barrel should be completly dry and clean.

Waldo, Mixed the WS2 & BN into a paste as well but didn't see it coat the barrel like I wanted. Mineral spirits works better for me.


JRS, why should the barrel be completely dry and clean when using BN?

I have not had a chance to try lock ease yet, but I have noticed that a light spray of Rem oil,in the green and yellow spray can that says with TEFLON lubricant) on a patch really seems to help it along. I think by the time the Teflon wears out, the barrel is coated with WS2. Today after a good barrel cleaning and finishing with the Rem oil, my coated bullets made a nice little group with the first 5 shots fired. That doesnt happen all the time though.

CPorter,
With a clean barrel, you allow the hBN to imbed itself into any imperfections that might exist in the steel. The bullet being the carrier. The dry barrel for the same reasons you dry patch your barrel before shooting in any discipline.

One does not want to leave anything in the barrel that is going to impede the lubricity of the hBN. Why would you want to coat your barrel when the hBN coated bullets are doing that for you?

You guys that like bullets that have a lubricant on them ought to try some wax. Wax will reduce the SD to nothing and copper along with it.
