WD-40 SPECIALIST DRY LUBE AS AN OPTIONAL LUBE FOR PURE LEAD BULLETS UNDER 1,000 fps.

[THE_ANTIDOTE]

Anyone try this? I was talking with a gentleman at the range this morning who said that's all he uses and hasn't had any leading/fouling. I was going to try making a little bit of lube at home and told him I got the wrong ingredients (beeswax and lanolin) when he asked why I don't just spray them with dry lube? I told him I'd never heard of that, his response was to buy some at Harbor Freight. I am shooting pure lead bullets out of magnum pistol caliber carbines in case that matters... I am also ordering White Label carnauba blue, but curiosity got the best of me.

For low pressure, low velocity (700-750 fps) wadcutter loads I've just given them a swirl with powdered mica.

Keep those pure lead boolits at 700fps to 750 fps ... Target Loads
Pure lead boolits can't take the higher velocity or higher pressure of standard pressure / standard velocity or Magnum loads ... they are Too Soft !

Usually the Dry Lubes are some form of Micro-Teflon in a carrier , the carrier evaporates and leaves a thin coating of Teflon ... Lead doesn't stick to Teflon ( I use dry lube on my boolit casting moulds as a release agent and rust preventative , great on sprue plates) Stands to reason it would lube a boolit ...
How well will depend ... I say spray some boolits , let dry and spray again ... load , shoot and report back .
Target Loads would be my first test .

It'll probably work, let us know if the PTFE builds up in the barrel.

When WD-40 dries it gets sticky, so it collects all the crud out of the air, not a good paring in a gun barrel.

I came across this while researching dry lube.
Amongst many other industrial applications, PTFE is used to coat certain types of hardened, armour- piercing bullets in the military and in civilian use to reduce the amount of wear on the firearm's rifling in expensive match grade barrels. These are often mistakenly referred to as "cop-killer" bullets on account of PTFE's supposed ability to ease a bullet's passage through body armour. Any armour-piercing effect is, however, purely a function of the bullet's velocity rigidity, nose shape and weight rather than any property of PTFE. Teflon coated bullets as a "cop killer" round is a 100% media generated myth.

This is interesting. Post #7 is the most interesting.

Yeah, I found that info on the Los Angeles Silhouette Club site. The Los Angeles Silhouette Club

I'v never tried shooting them with just dry lube , I do use it for sizing.

When water drop'ed I dry them and spry them and run them through the push through sizer as soon as I can before thy start hardening. These thing are so slick you can't hardly pick them up with your fingers.

With a second coat it might work . I normally put another lube over it . Ether with the lube-sizer or lately BLL .

Thank you for posting that. I will stay with the old lubes that has worked for decades or BLL

I have been quite happy with the speeds you can send soft lead bullets when properly cured with powder coat or spray enamel paint .

I have never had much luck with any of the dry lubes for high velocities weather home done or on some older swaged bullets . I have some Hornady bullets around with powdered graphite they made a terrible mess of the bore on my S&W model 28.

Above Teflon is mentioned I once took some hard cast .38 caliber 160 grain bullets and double wrapped them in Teflon tape then swaged they to .452" . I loaded them to 1100 f/s the first three touched on a old phone book at 15 yards then the shots went wild . All the recovered slugs still felt slick but my 1911 bore was badly leaded. I have since then bumped up coated bullets with good luck and before that I had taken lubed gas checked .38 bullets and swaged them and they shot well . The lube grooves get thinner and the gas check gets bigger but they shot well .

There have been a few articles over the years in American Rifleman. going back almost 50 years, about using Teflon for bullet lubes. Iirc, theres even an article in one of their old reloading tomes.
Might want to google that.
