What would be a quick / easy way to clean that black/tar like substance off of a large quanity of pulled military bullets ? I assume it is a water proffing selant. I'd like to get it all off before reloading the projectiles. Thanks
You do not give an approx. age of the projectiles. So... Back in the days of Jack O'Connor et al, they used to talk about asphalt. So I would suspect that any standard solvent, kerosene, gas, carb cleaner, WD 40, might cut that old stuff. Now today with the onslaught of plastics, then you might need something with more "horsepower" and I am guessing the bullet/bore cleaner solvents should be enough. Again, there is an aerosol "carb cleaner" by GM that is suppose to be the same stuff as Shooter's choice, in an aerosol and cheaper (then anyway)... Old .30/'06? I would start with Kerosene. Today's .223? Move quickly to the bore cleaners or.
And, if nothing else is attacking the coating, the ammonia based will attack the jacket, the copper alloy, and get it off that way. Beware. That might reduce the diameter of the bullet too enough to be a problem. luck.
