Lanolin has been used for ages, that's not by chance. Can be used neat or mixed with petroleum jelly, or with IPA/alcohol as a (shake and) spray-on
lube.
Soaps are also usable, RCBS water-soluble lube feels a lot like liquid dishwasher detergent and I have heard of people using that with good results.
I've also heard of people getting stuck cases, so your mileage may vary.
The last class you could look into are EP (extreme pressure) additives. One of the oldest synthetic ones is sulfurized vegetable oil, these are
excellent cutting oils. Basically rape seed oil (canola) with 5-10% sulfur added. Then heat slowly until it dissolves and hold for a while. If the
sulfur precipitates out again on cooling increase temperature a bit. |
