Fed Premium has secured a U.S. Navy contract for delivery of $20 million worth of frangible .40 S&W cal. rounds featuring Fed's new lead-free "Catalyst" high performance primer. Other manufacturers of lead-free primers are hydroscopic (attracting moisture), and subject to failure.
Lead styphanate has been the staple chemical used in primers for years. Prior to lead styphanate, Mercury Fulminate was the go to substance, but it is corrosive, leaving an acidic residue in bores of barrels.
Federal Premium's Catalyst primer is not hydroscopic or corrosive, and supposedly delivers clean and reliable ignition. The U.S. Naval Surface Warfare Center-Crane Division will receive rounds beginning 2018, and continue for 5 years.
Does ocean salt water make salty moisture?????

Awhile back Browning A-5's had an issue with their stocks turning whitish under the poly finish coat. They said it was because the wood (walnut?) was salty. A recall ensued. I never understood, and still don't!!

The stock wood supplier salt cured the wood in order to rush the curing/drying time. Since wood is like a sponge, salt was absorbed and then leached to the surface later, with horrible results. Makes for some interesting googling.
