Lee Liquid Alox Bullet Lube coats the entire bullet in a very thin film of lubricant. This thin film dries to a soft, varnish-like finish that really adheres to the bullet. Additionally, the dried coating will not affect powder. Easy to apply and eliminates the need for sizing of most cast bullets. While it works well with all cast bullets, it works best with the micro band bullets, which are designed for tumble lubing.
