I normally make my lube 70% coconut butter, 30% beeswax and it lubes good through the #45 in cooler weather. But today I went 50/50 with a tablespoon of Mobil 1 syn oil. In the mid 60s here today and made a hot pour in the #45, was hard when it set up and could not lube without a 100 watt light bulb and aluminum foil warming the #45. I thought a little Mobil 1 would mitigate the 50/50 mix somewhat, but it never worked out that way. Got a good stick in the boolit lube grooves and should be good to go better than my 70/30 mix comes the 120 degree weather.
