Things I have learned from processing 1X LC 308 cases is that it is best to clean the cases in walnut hulls in a vibrator type case cleaner, then use Imperial Case sizing lube. The only problem with Imperial was it was really hard to get off the cases ** It wasn't till I tried the cleaner "Simply Green" that my cases were clean with no sign's of the Imp.lube. I take the 2-300 cases I have sized, dump them into a 5 Gal. bucket, pour in a cup or so of "simply Green", swirl the cases around , or stir for about 3 Min. Add enough water to cover the brass, stir for another 3 Min. then use a strainer to save the water fot use with 223 cases. Fill the bucket about 3/4 full of water stir then drain. pour the cases on a towel in the sun and let dry. ** Some will say just wipe it off, ever try to wipe 2-300 308 cases ??
