Molly Moly

Molly is nice.  We like Molly.

This is a Molly we can get behind.

This is a Moly really don’t like.

molybdenum disulfide

Moly in Firearms has been a popular topic of debate in the Gunverse.  It has good lubrication properties, but it also has some problems.  The main problem that I’ve seen is that molybdenum disulfide offers a road into the metal for corrosion.  Moly is hydroscopic.  This means it attracts and retains moisture right out of the air.  Moisture will attract grit as well, and this can increase the friction you are trying to get rid of.  This is less than ideal. This was explained to me by the late Gale McMillan.  So if you are going to argue with him, you had best know more about rifle accuracy than him.

A lot of people are using Moly on their bullets.  This can increase velocity, help accuracy… and that’s a good thing. Probably the best use of Moly when it comes to firearms.  Unfortunately Moly gets hard (it’s a crystalline mineral after all) and builds up.  This leads to problems, reduced accuracy, and irregular bore wear… which can ruin your rifle.

I’ve got a lot of emails from people who are guessing that Slipstream is Moly.  Gundoc put it best. “Moly is for Chumps.”  No.  We do not use Graphite or Moly.  Or a Mixture of the two.   We don’t like Moly.

Molly however… Shivers our Timbers.

  1. I am very cross with you for lowering yourself to such a gratuitous and exploitative way of attracting attention and having it work on me… very cross indeed Sir!

    1. I only speak the truth of this matter… and you have seen it. You can not disagree with the truth. If you do, you only argue opinion. FACT: Molly is awesome.

      1. I hope she’s not someone you actually know, but honestly, as lovely as the blessing of youth make her, in this photo at least, she looks a bit dense.

        I say this as someone who once made a living taking photos of very attractive women.

        She isn’t really that appealing to me.

        I am of course open to further research into he matter.

        Also, I have learned the hard way to avoid women with knives.

        It’s only sexy when they’re stabbing someone else.

        1. 1: readily taking up and retaining moisture
          2: taken up and retained under some conditions of humidity and temperature
          That’s just what it means… from the link I put there. WTF are you getting on about?

  2. It’s pretty easy to figure out what is in slipstream. Anybody who thinks it’s Moly is a little silly. Moly and graphite are the WD40’s or duct tape’s of the dry lubricant world…it gets the most press but are not very effective.
