I have been given a quantity of candles made from paraffin and was thinking of melting them down and combining 50/50 with petroleum jelly to use as a lubricant. Intended use is for smokeless military rifle calibres using approx. 16 grains of 2400. Is this feasible as there seems to be divided opinion on paraffin based lubes. Do I need to add anything else? Also thinking of using it in mild pistol loads.
