Popular Lubricants for Case Sizing and Neck Turning

There are many products used successfully for case lubrication for case sizing. And for neck-turning a variety of lubricants are favored. The video above explains the basics of case lubrication with die wax, and spray lubricants. Below we mention three products that have proven very effective. For cases that have a close fit to your chamber via custom FL dies, Ballistol works well and is easy to apply and remove. For neck-turning, some of our Forum members have had great success with some automotive lubricants.

Three Good Lubricants You May Not Have Tried Before
If you’re using a body die or a full-length sizing die, try using Ballistol (in the aerosol can) as a lube. It works GREAT without the tacky or gooey residue left by most case lubes. It will also clean off carbon residues on the neck as you lube the case. Just spray a little on a cotton patch (or your fingertips) and wipe each case before you run it up into the die. If you are using a steel neck bushing, be sure to wipe the neck as well. You can usually do a half-dozen BR-sized cases before you need to re-apply Ballistol on the patch. Ballistol is non-toxic, bio-degradeable, and will not harm your skin. It is very slippery, but can easily be removed with a rag or paper towel. Try it–you may retire your One-Shot. Ballistol can also be used to protect wood stocks.

Note, for heavy case-forming or necking up case necks, we still recommend a thicker lubricant, such as Imperial Die Wax. But for normal case sizing, after your neck has been expanded, Ballistol will do the job, and you won’t need to tumble the brass afterwards. All you need is a very thin layer of Ballistol, and this easily wipes off with a paper towel.

For Neck-Turning, Try STP Blend or Assembly Lube
For lubing the neck-turning tool mandrel while turning case necks, many folks use a blend of STP® Oil Treatment and Mobil 1 lube. Chuckw2 reports: “Try STP and Mobile 1 Synthetic oil in a 50/50 mixture. Very slick, you will need to tumble your cases after turning.” STP is a very thick lubricant, that flows and clings almost like honey. Jason reports the STP blend comes off easily in an ultra-sound bath, using a bit of detergent. At many retailers, STP is also available in a convenient 7-ounce tube, so you don’t have to buy a large bottle.

Another even cheaper option is assembly lubricant. For turning his case necks, RStreich uses assembly lube from an auto parts store. He notes: “The brand I have is reddish in color and kind of sticky like honey. It’s far better than the Imperial die wax I was using before.” There are a variety of types, both with and without moly additive, and you can select the viscosity you prefer if you sample a few brands. Be sure to clean out any lube residue from the inside of your necks when you have completed your neck-turning.
