Just remember there's a big difference between soft lube, low-viscosity lube, and slippery lube. Soft lubes that jettison well at low pressure are generally too slippery due to high oil content and relatively low soap content, or have a lot of Lithium soap which itself is slippery when thin and hot. Low-viscosity lubes generally don't handle boundary conditions or high velocity very well, but do jettison well due to almost instant melt characteristics. Slippery lubes can be hard or soft, and can work in very specific and highly tuned setups, but are usually poor for general use. Making a lube that is soft, not too adhesive or cohesive, is thixotropic, yet still has very predictable and repeatable boundary lube characteristics through a broad temperature range is really pretty tough to accomplish.
When lube is crushed out thin and all the wax melted, what's left on the boundary is what makes the difference in how it shoots. Things like castor oil, lithium soap, sodium soap, Lanolin, Carnauba, graphite, zinc compounds, Moly powder, and Paratac all start to go to work as the base oils and waxes thin out past their ability to give a good dynamic film. If you push sodium soap lube past the boundary film capability of the oils, it dumps out and leaves fouling. Lithium soap lube doesn't have that problem unless waxes are below 10% by weight. But Lithium soap gets slippery when very hot, and hydroplaning or the famous 'lube smear' can start to occur because the molecule is about 100 times smaller than sodium soap. Sodium is a better "stop leak" but the matrix gets wrung out of oil easily like a sponge, so you have to support it with castor oil (only thing I know of that has the correct molecular polarity for the job).
The reason I mention all this is to explain the qualities a lube must have to be able to jettison easily from deep grooves and not be either too slick or too "purgy" when used in excess quantities. Many of the lithi-bee derivatives will goober up a revolver very quickly using big square-grooved bullets, and may or may not shoot well depending on the quality of the lube, the temperature, and what the revolver likes, so it's very easy to trade late-jettison flyers for purge flyers and actually have worse groups with a softer lube.
