bullets lubes
« on: December 04, 2009, 09:17:17 AM »
Hi Veral
in several forums, some persons shares their ideas and debates about the bullet lube fonction.
Is it a lube, an anti seize, an anti flux or a gas seal. ( or all together)
I would be happy to know your opinion

  I don't give out opinions, or theory, only knowledge.  If I don't know for a fact, I have no problem saying so.  When I do know for a fact, I get mouthy and put opinions and theory down.  I wasted many hundreds of hours,  thousands of primers and pounds of powder experimenting on theories promoted as if they were fact, so excuse my bluntness or not, I speak what I know.

  Bullet lube has NO gas sealing power or effect.  Some say or think, or theorize that it does, but consider the fact that the hardest hydrolic seals won't seal off leakage at pressures much over 10,000 psi and we are working with up to 60,000 psi!  The best bullet lube on earth cannot seal off gas if there is any gap at all for it to pass through.  The seal must be with the bullet alloy.

  Anti flux?  No and this isn't worth debating beyond stating that the lube must NOT be a flux.

  Anti seize simply means lubricate well enough that metal doesn't gall under friction.  Maybe of interest here is the fact that lead, in white lead form, is the best antiseize lubricant known.  All lead is a superlubricant under extreme pressure, but white lead is easily applied with a brush and sticks under the extreme pressure of putting high interference parts together.  The issue with lead against steel bores isn't galling but melting of the lead due to friction.   With cast bullets, we aren't working under the super extreme pressure of high interference part pressing, but fairly high pressure combined with extreme speed.  If the lube fails, an extremely thin amount of lead melts due to friction and is deposited on the bore.  We call the residue bore leading.  It is not what is called galling, which happens even at very slow speeds, measured in inches per minute.

  So, bullet lube is a lube and it's lubricating strength dictates it worth.  Experimenting in any other direction with 'lube' will waste your time.

  Many want to save a few coins by making lube, but I recommend against it.  If you are shooting at low speed where lube requirements aren't extreme, but are getting any leading at all, try tumbling lubing as I explained in another post, using LBT lube, or try melting about 25% LBT lube with whatever lube you have that's cheap.  The results will amaze you.  If you want to power your bullets up, use LBT lube without dilution. 
 
  Developing a good bullet lubricant is too expensive and unprofitable for the big boys to mess with.  I was stupid, 30 years ago, when I thought I'd get rich quick if I developed a lube that prevented leading.  Doing so cost us our life savings and 6 months, working 12 hours a day, 6 days a week.  I expect it took at least 15 years for all that effort and expense too come, back, if it ever did.  I've been most comfortable not knowing or trying to keep track.  I do clearly remember though that advertising costs per stick sold were so high that it cost me $15 per stick shiped it for quite a while!

  I don't believe it possible for anyone to develop a better bullet lubricant than the LBT lubes, and, if someone ever does, I don't know what the improvement to performance could be.
