At the NDIA conference, Nammo gave a presentation on their new lineup of armor-piercing ammunition. Nammo produces both the tungsten cored AP rounds in use with the US Armed Forces: The 7.62mm M993 and 5.56mm M995. Aside from data on these previously enigmatic round types, the Nammo presentation also covers new round types they have introduced, such as the “Power Ball” tungsten-tipped ball ammunition for 5.56mm and 7.62mm:

Nammo’s efforts are evidently focused on reducing the cost of ammunition that incorporates tungsten in its cores. The company is developing a sintering process for tungsten that does not use cobalt as a binding agent, replacing that instead with either iron or nickel, both much cheaper than cobalt.
