Dougy Posted August 7, 2016 Report Share Posted August 7, 2016 Has anyone done any testing using HBN as either a bullet coating or barrel treatment ? My initial trial using it with my 17_Remington looks very promising. 20 shots before coating with HBN and then cleaning using bore foam showed normal expected blue patches. Taking 12 patches to get to minimal marks remains. After coating bullets and patching the barrel through with HBN 20 shots again, and the same treatment and soak time with bore foam, then just 5 patches and very very little sign of copper showed on patches. More testing with a chrono and paper to be done, but if it keeps the fouling down on the 17 it's and keeps accuracy up I'll be using it all the time.

LeadWasp Posted August 8, 2016 Report Share Posted August 8, 2016 Richard Utting did some videos about this on Youtube. I have wondered about it, and I've also wondered about the effect of the dust on health. If it's <50u then could be quite nasty during bullet prep. HBN seems to have dropped off the radar a bit lately. Quote Link to comment Share on other sites More sharing options...
Dougy Posted August 8, 2016 Author Report Share Posted August 8, 2016 I will be wearing some appropriate dust protection from now on thanks LW. Quote Link to comment Share on other sites More sharing options...
LeadWasp Posted August 8, 2016 Report Share Posted August 8, 2016 (edited) I know it might sound a bit daft on the surface but a random ceramic (in the industrial sense) powder, and very finely divided stuff too, could be a potential problem. HBN is not a known carcinogen, nor is free boron likely to be liberated when shooting but a fine dust is still not good news. It's only that I care John ;-) You might find Boots Talc is just as good.................talc is after all a lube too and it has a low carbon footprint.

mick miller Posted August 9, 2016 Report Share Posted August 9, 2016 Not wanting to widdle on anyone's biscuits here but... is this really that necessary? Pardon my ignorance, but I have never heard of anyone doing this, even on the range, even with custom rifles. Does it add that much to barrel life and, if it does, where can I read up about it please? Quote Link to comment Share on other sites More sharing options...
Dougy Posted August 9, 2016 Author Report Share Posted August 9, 2016 Mick miller Have a look at Richard Uttings reports on the Coating of bullets. www.youtube.com/watch?v=rDHYzGg7Ucc (restricted at work so may not work) The initial reason was due to the fact that I chose the 17 Rem, they are renown for the speed of bullets "and" the speed of which the barrel fouls up. It was recommended by a pretty decent rifle smith and shooter that I should give it a go if only to reduce the fouling. I have only done the 1 test and that certainly showed promise, if it reduces the fouling for me it has to be a bonus. Accuracy has yet to be checked as we are all fully aware its worthless if you cant hit the target. There are a few shooters out there that I am sure that use it but do not shout about it. Have a look at www.longrangeshootersofutah.com/boron-testing bulletin.accurateshooter.com/tag/boron-nitride www.6mmbr.com/bulletcoating.

mick miller Posted August 9, 2016 Report Share Posted August 9, 2016 And it's a one hit, permanent application? Or does it require frequent 'topping up'? Quote Link to comment Share on other sites More sharing options...
Dougy Posted August 9, 2016 Author Report Share Posted August 9, 2016 Actually the good thing is that it's easily cleaned out. Unlike moly. 100 grams will coat approx 1500 bullets roughly. Maybe more as i will be using it mostly on the small 17 caliber.. Cost is around £35. Quote Link to comment Share on other sites More sharing options...
mick miller Posted August 9, 2016 Report Share Posted August 9, 2016 Okay, reads well but perhaps I'll save this for my 6brx... when I can afford it! For rabbits and vermin it might be a bit too anorak even for me, and I like a good anorak ! Quote Link to comment Share on other sites More sharing options...

Dougy Posted August 9, 2016 Author Report Share Posted August 9, 2016 Rather spend more time shooting than cleaning it. Which is what the thought process is behind it all. I'll let you know how I get on.initial trial is looking good. Quote Link to comment Share on other sites More sharing options...
Dougy Posted August 9, 2016 Author Report Share Posted August 9, 2016 (edited) I've spoken to precision ceramics today and I'm assured it's not caronagenic as it's used a lot in makup. And yes I'm expecting some comments regie. Silly spelling Edited August 10, 2016 by Dougy Quote Link to comment Share on other sites More sharing options...

mick miller Posted August 15, 2016 Report Share Posted August 15, 2016 Not necessarily, many classes hold an over 50s session. The flatulence may be more extreme than usual, but the results can be just as impressive. Quote Link to comment Share on other sites More sharing options...
Dougy Posted August 20, 2016 Author Report Share Posted August 20, 2016 I've not long cleaned my 17 remmington after using HBN in the barrel and coated bullets. A 1/2 hr soak with forest foam and no sign of copper 6 patches and all clean. Then put 3 patches soaked in Sweets copper removal another 1/2 hr soak and still no sign of copper after another 6 patches. So far it's looking very impressive.

Dougy Posted August 21, 2016 Author Report Share Posted August 21, 2016 (edited) Out last night on the bunny's, 34 shots for 30,furtheSt was 245yds pretty good considering the weather conditions, heavy showers and the moderate winds. Cleaned this morning, Bottom row from the left. 3 when I got in at 12.30, next 4 bottom row after 3/4 soak with for rest foam this morning. Middle row from the left. 25mins soak with KG12 Copper remover. Top 4 clean out with acetone. The odd one on the right is a patch I used to apply the HBN to the barrel. I also coat the bullets in a tumbler and 4mm steel balls sealed in a plastic tablet container. Edited August 21, 2016 by Dougy Quote Link to comment Share on other sites More sharing options...
