I have a pound of soy wax left over from another venture and I have been giving some thought to soft lubes for use in cold weather rifle applications, specifically for hunting with cast in 358 Win. My general experience has been that soft lubes are better performers than hard ones in rifle applications, provided other conditions have been met. Soy wax is a very soft wax as compared to the other traditional wax bases, which has an advantage if you want it to fling off as soon as it leaves the muzzle, but in researching it I have found that it has a melting point of only 120-130F depending on the particular blend.
I made a very conservative test batch of 8oz (weight) soy wax and 2 oz (fluid) of synthetic 2 cycle oil and it is very soft. I have no idea how it shoots, it since the temps have been in the single digits here I should be able to conduct some good tests. I think the handling qualities will require handling and storing them gently, but that's OK for small quantities of hunting boolets. My worry is that I might forget and leave a box of stored loaded rounds in the trunk or in the garage in the summer because with a melting point that low the wax base would surely liquefy and contaminate the powder charge.
So here's my question: is there an ingredient I could add that will bump up the melting point somewhat without also increasing the hardness too much? I know it doesn't take much carnauba added to a beeswax based lube to make it require a heater, so that's not my first choice. Maybe a little stearate? Or would that add too much stiffness too?
Advice?
