Those of you who used surplus pulled M118 / M72 173 gr Match or other pulled GI bullets have probably been baffled about how to removed the asphaltic sealant from the bullets. The safest way is to get a bottle of Orange Clean Concentrate http://www.greatcleaners.com/ogi_retail/product.asp?catalog%5Fname=ogi&product%5Fid=17101 and mix it 1/100 with water. Drop bullets in a salsa jar, mayonnaise jar etc and allow to sit for 24 hours. The following day agitate the jar and the mouth lacquer will literally fall off in flakes leaving the bullets not only clean but nice smelling. Unlike lacquer thinner which actually doesn’t work very well, this method is not flammable nor a breathing hazard.
You will need: a carton of BBs. (costs about five bucks from Walmart), a rock tumbler (flea markets, ebay, and commercial vendors), and a bottle of Ultra Ivory dishwashing detergent.
With a small rubber drum ( 1 1/2 lb size) tumbler add maybe 200 BBs, 100 pulled 173s, fill with hot water to just above bullet/BB level. Add about a tablespoon of ivory liquid and seal the drum with the screw lid on and put on tumbler and let it tumble for about an 45 minutes and check. (Mine come out looking better than new Sierra Matchkings) Take the bullets out with you fingers and dump in rinse water. Add another hundred bullets and tumble the next batch. Solution good for a number of cycles. When you finish dump the solution in a big jar and save it for washing your tires or something real greasy down the road. When you are not tumbling remove the BBs and dry them. If you have a bigger tumbler you can tumble more bullets.
Making up a Pre Tumble Dip with Ivory and letting the bullets soak a bit before putting them in tumbler might cut down the operation to less than thirty minutes.
