Coating Bullets with HBN

[TonyR]

I would like to try coating some bullets with HBN but I don't know what particle size to buy. The supplier listed in the Accurate Shooter "How-To" lists 4 different partical sizes and purities. What size particles are people using?

The stuff I'm using is labeled as "HCPL Grade".

Tony,

The really fine stuff, 70 nm, is what you want.

The -5 Micron is working well for me. You can get a 1# sample fromhttp://sandblastingabrasives.com/hexagonal-boron-nitride-powder-order-page-781.html and it will last along time.

I have a lot of the 70 nm left over. if you'de like to buy what I have left, almost a pound, let me know and we can arange something. I purchased it from lowerfriction.com. it worked well for me, I just backed off on the amount I'm shooting lately.

Thanks everyone for the replies. I have ordered the 70nm from lowerfriction.com and the steel balls from Neconos.
