Make Your Own Case Lube

Over the years, I’ve used quite a bit of spray lube for case sizing, most of the time Hornady One-Shot for pistol, and Dillon DCL for rifle. As my supply of Dillon DCL dwindled, I started looking at other options. Dillon DCL has worked well, but leaves a sticky residue that’s hard to wipe (or tumble) off the cases. Then I talked with the 6.5 guys who swore by (not at) their home brew lanolin case lube (a formula they found online if memory serves).

Per the 65guys instructions, I ordered the same components and spray bottles, and these worked out great:

As shown in the video, I found the following process to work well:

  • Draw a line marked “alcohol” 4″ up from the bottom of the spray bottle.
  • Draw a line marked “lanolin” .4″ up from the alcohol line.
  • Fill the bottle with 99% isopropyl alcohol up to the alcohol line.
  • Pour lanolin into the bottle until the fluid level is at the lanolin line.
  • Gently shake/tip to mix until there’s no lanolin at the bottom of the bottle.

That’s it! Your case lube is ready to use! Just put some brass in a bin, spray, re-arrange, spray again, then wait 5 minutes for a quick flash-dry. Hope you find this useful!

Anyone else out there using homemade lanolin case lube? Please share your experiences!

Thanks,
Gavin

    1. If I had allergies to lanolin, I would wear disposable nitrilel gloves, and be careful of any overspray. I would also wear a respirator that filters out particulates if need be.
      Hope this helps.

  1. Thanks for posting this and I will be trying it. However, the hyperlink takes you to the Amazon site for a single bottle of Alcohol. Here is the correct link to Amazon for the Alcohol 2 pack which is much cheaper than what the link in the blog takes you to. Why Amazon has the same product at widely different prices escapes me.

  2. I make my own lube – very similar to what you just presented. I can never find 99% Isopropyl, so I use Iso-heet which contains 98.5% Isopropyl alcohol. Works great, makes a lot and is just as good as commercial versions but for a lot less money per ounce.

  3. What is the downsize of using 91% Isopropyl Alcohol instead of 99% since 91% is typically available in local drug stores?

  4. I’ve been using homemade lanolin case lube for a couple of years now. It’s important to note that you want to get the 99% Isopropyl and not a lesser grade. The lower grades (70% is most common) have water in them which will make the case lube separate like oil and vinegar salad dressing. You will probably have to get the pharmacist to order it for you.
    I mix mine 4:1 and it only takes a little. I tried 10:1 but that lead to a stuck case.
    I put the cases, 100 at a time, in a 1 gal. zip lock bag and spray 2-3 squirts with the nozzle set to fine mist. Roll the cases around for a bit and then open the bag and let the alcohol evaporate for a couple of minutes. If you have lube puddled up in the bottom of the bag, you used too much. The proper amount is when the cases feel greasy, but don’t look greasy.

    If you’re using SS pins in your tumbler, wipe the cases off good before tumbling, otherwise they come out dull.

  5. What would be the impact of using 91% Isopropyl alcohol instead of 99% since it is available in my local drugstore?

  6. A really good and fast way to lube cases…I mix 70% alcohol and lee case lube in a spray bottle…it dries very quickly and is water soluble which is important to me since I use a RCBS sidewinder tumbler and liquid media

  7. I have had great luck with RCBS Slick Spray lube, but have also followed the same recipe.

    I prefer using RCBS with a pad for lubing inside the necks, (I just put a liberal amount on the pad and push the neck into the pad to get it to lube the inside) Simple and pretty clean.
    I also use a spray or two of slick spray for pistol brass just to reduce the effort when sizing with carbide dies.
    Thanks for all the info.
