Dozens of different liquid neck-turning lubes have been used successfully, including blends of Mobil 1 motor oil and STP, as well as various “secret recipes”. This Editor’s preferred lube for “skim” neck-turning, where only a single light pass is required, is Prolix Xtra-T lube. This is a thick, blue-colored lubricant that contains a bit of paraffin. It is VERY slippery, yet because of the paraffin it stays in place on the mandrel (arbor). It comes in a 1.25 oz. plastic bottle with a handy extended “needle-nose” applicator tip. The long-nosed tip makes it easy to apply lube inside a case neck, or to very precisely add a small drop right ahead of the cutter tip on the neck-turning tool. Xtra-T lube is also a good general purpose lubricant that nicely fills the gap between a grease and a typical oil, and it works well on pistols too. In consistency, Xtra-T lube is similar to molasses. It flows like a thick oil, but it has good adhesion because of the paraffin component in the blend.

I’m not suggesting Xtra-T is the ultimate “miracle” neck-turning lube. There are many other good options. But Xtra-T applies easily, stands up to heat, stays where you put it, and works great as a general-purpose lube as well. You’ll find Prolix Xtra-T lube in many shooting supply stores or you can order directly from www.ProlixLubricant.com. The small bottle with applicator tip costs $6.99.
