This is what I use:
BRASS SPRAY LUBE FORMULA _ 1 part liquid lanolin and 4 to 5 parts parts 99% isopropyl alcohol. Do not get alcohol less than 99%.
Pure Liquid Lanolin mixes better if you warm both the alcohol and lanolin in a bath of warm water to about 105 - 110 degrees F before mixing. DO NOT WARM EITHER OF THEM OVER AN OPEN FLAME! When warm, pour together, mix thoroughly, allow the mix to cool (mix occasionally as it cools) and store in an air tight container to prevent water from being absorbed by the isopropyl.
Am using this formula with perfect results for my .223 & .308 brass. Its extremely economical and effective. Happy re-loading!!!
