Frankford Arsenal CleanCast Lead Fluxing Compound - 1 lb Premium Casting Flux

If you're casting your own bullets, the quality of your molten lead directly impacts the consistency and reliability of every round you load. The Frankford Arsenal CleanCast Lead Fluxing Compound is a lead casting flux designed to clean your alloy by separating dross and impurities from usable metal, giving you a cleaner melt and more uniform bullets downrange. Unlike older homemade flux methods—rosin, paraffin, tallow, or bullet lube—CleanCast does its job without smoke or odor, making your casting sessions more comfortable and your workspace more pleasant.

Bullet casting is a rewarding way to reduce ammunition costs and dial in loads exactly to your rifle or handgun, but it demands clean metal and consistent technique. Contaminated lead creates inconsistent melts, poor casting flow, and bullets with surface defects that affect accuracy and function. This flux works on the chemistry of molten lead to help float dross to the surface where you can skim it away, leaving you with purer alloy for each casting session.

A little goes a long way: one pound of CleanCast is enough to flux multiple 20-pound lead pots, so a single container will serve most home casters for a long time. If you're serious about handloaded ammunition quality and tired of the smoke and smell that comes with traditional flux methods, this is a practical upgrade to your casting bench.
