SOCOM experimenting with Bullets that Shoot Thru Water and Other Material.....
U.S. Special Operations Command, or SOCOM, has begun experimenting with new bullets that could allow frogmen to shoot up into enemy boats or helicopter gunners to strafe periscope-depth submarines.
How does it work? The tungsten-tipped CAV-X bullet from Virginia’s DSG Technologies has a nose that creates a small air bubble as it moves through the water. The bubble greatly reduces drag on the bullet, a supercavitation effect that has been part of torpedo design since World War II and is now a feature on some types of boats.
The company also demonstrated different bullets that can shoot through sandbags, through 2 cm of steel (with no ricochet), and through body armor.
DSG is also selling to other governments, Leonhardsen said. He declined to identify them. He did say those governments were testing how well the bullets performed when fired from helicopters into the water. One potential target: submarines. In tests performed by DSG, the .50-cal. bullets can travel 60 meters through water or penetrate 2 cm of steel through 17 meters of water.....snip~

We should talk to US Weapon Companies, and get the thought across to them to not sell to other countries.
