HBN application question

[Keith Glasscock]

I'm trying HBN on a few Berger hybrids. I'm planning on using it exclusively in a barrel that has yet to be chambered.

After 3 hours of application time, it all seems to wipe off during the cleanup. The color of the bullets is slightly different and they are slick.

I did start by cleaning these samples with alcohol before applying HBN.

Did I apply it correctly?

Probably, they should have a satin or cloudy look. If you are used to the look of moly, then I understand why you think the coating may not have taken.

Thanks Bill,

I threw the same 7 bullets back in for another 9 hours just to see what would happen. They came out with a rough, white coating. It is so thick that I can feel the texture with my fingers. I suspect that I had way too much HBN in the container and ran it way too long. For my purposes, these bullets will do fine.

I'm intending to break in a new 284 barrel with naked bullets and get a basic pressure vs velocity before cleaning it and putting HBN in. My idea is to see if the HBN will make the upper node useable (2920) without sacrificing cases. These 7 overdone bullets will be used to season the HBN into the barrel.

I would think seven hours would be way to long I get good results after about 1 hour in a jar of BB's with about as much HBN as i can get on the end of about 3/8 of an inch of Popsicle stick in a Thumblers Tumbler, I use large peanut butter jar wedged in the tumbler fits nice and snug this would be for 100 bullets. They come out all dusted and spotted all over which wipes off to a satin sheen
