Many have used store bought and lanolin homemade case lube. I have been trying lots of combinations of case lube from cooking oils to other natural oils. I think I may have found my new go to and it is Coconut oil. You can find it in just every store in the baking section. It is both sold in a Crisco type consistency and a clear oil. I tried the coconut crisco type just by using a small brush and brushing each case. Worked excellently smoother than one shot and other lubes. The coat is almost so thin you can only feel how slippery it is. After running through your die just wipe the case clean. The other coconut oil I tried is clear and a liquid. I mixed it at a bout 20% to 80% with 91% rubbing alcohol. It really needs to be emulsified so I used my blender. Put it in a small spray bottle and squirted it on the cases, let it dry and ran through smooth as silk and wiped them clean. It now is my primary case lube.
