dylan5588 Posted August 7, 2014 Report Share Posted August 7, 2014 Hi, Anyone have any experience using Boron Nitride lubrication for bullets and/or bores? it has been suggested that it may help protect the throat from erosion as it is resistant to up to 900 degree celsius temps.

DaveT Posted August 7, 2014 Report Share Posted August 7, 2014 Very easy to apply using a tumbler, jar and small ball bearings (probably shot or BBs would also work but might be a bit soft to 'hammer' powder into bullets) and very clean (unlike Moly!) ......only time will tell if it is as effective as claimed but I am sticking with it on a 6mmSLR and Dtacs.....early days results show very little fouling occurs. Expensive to buy but a little will last a lifetime. Link to comment Share on other sites More sharing options...

DaveT Posted August 7, 2014 Report Share Posted August 7, 2014 To be honest I have seldom experienced the fabled cold bore shot problem...I am more inclined to put that down to a 'cold shooter' who has not got his eye in yet. I am more interested in the suggested increase in barrel life especially for calibres liable to be barrel burners. Link to comment Share on other sites More sharing options...

As you say "time will tell" I will do some more research, and maybe give it a try, Regards Adrian Link to comment Share on other sites More sharing options...
Davy Posted August 7, 2014 Report Share Posted August 7, 2014 My experience is Hbn is best applied using clean ceramic media, I keep things separate by bunging it in sealable vitamin tubs and use a timer to control the tumbling duration. Link to comment Share on other sites More sharing options...

DaveT Posted August 8, 2014 Report Share Posted August 8, 2014 I use a bore mop coated in Hbn to coat the bore lightly before I fire rounds. You can buy sprays but I would not want a lube getting into the chamber. Link to comment Share on other sites More sharing options...
firestarter Posted August 8, 2014 Report Share Posted August 8, 2014 I use HBN and find it very easy to apply and def causes less fouling. The down side is you have to buy a shed load of it....i have enough here to last me a lifetime! If you'd like some to try let me know. Link to comment Share on other sites More sharing options...

Many thanks for the offer, i have had some given to me to try, just needed some advice from people that have had first hand experience, Thanks to all who have replied Regards Adrian Link to comment Share on other sites More sharing options...
