    Supposedly . . this is the new 6.8 cartridge developed for . . whomever. It is a 6.8mm (.277") and the body of the case is polymer. Hopefully it will not stay white to the troops.
    This IS NOT based on the 6.8SPC chambering. --- SAWMAN

    Personally . . . I have never heard of any depleted uranium rds except for tanks and the 50BMG. --- SAWMAN
    Sea wiz anti missile, plane turrets use that type of ammo. Navy. 20mm.

    The gun subsystem employs a gatling gun consisting of a rotating cluster of six barrels. The gatling gun fires a 20mm subcaliber sabot projectile using a heavy-metal (either tungsten or depleted uranium) 15mm penetrator surrounded by a plastic sabot and a light-weight metal pusher. The gatling gun fires 20mm ammunition at either 3,000 or 4,500 rounds-per-minute with a burst length of continuous, 60, or 100 rounds.

    We had to move it around the armory on a regular basis while wearing rad badges. Cases were 120? Rounds and weighed over 75 lbs. Seems like that's right. When the badge turned pink you were removed.

    We have a real problem in the US with depleted uranium. What better way to solve it than load it into a gun and shoot it at people in foreign countrys.

    The plastic round idea is great. No more people (kids) scaving brass off the ground in hot zones. Also they are no reloadable, and leave em white in color. Seems like Brazil uses them with great success. (They work)

    And the wind will blow and they will want the creed more round. Hell walk into any gunshop and you'll hear the legends of the 6.5. I think you just stop the truck, point rifle out the window, shoot and a 12 point falls into the bed.

    Some thought that the illnesses associated with gulf war were caused by depleted uranium. It was and maybe still is used in armor.
    If the projectile is intact that is one thing, but if fired at steel the DP burns and giving off a fume of small radioactive particles and also the uranium by itself is poisonous in addition to the radioactivity.

    https://www.ncbi.nlm.nih.gov/books/NBK158798/
    Because natural uranium produces very little radioactivity per mass of uranium, the renal and respiratory effects from exposure of humans and animals to uranium are usually attributed to the chemical properties of uranium. However, in exposures to more radioactive uranium isotopes (e.g., 232U and 233U, and combined 234U and 235U in enriched uranium), it has been suggested that the chemical and radiological toxicity may be additive or may potentiate in some instances. In these instances, this dual mode of uranium toxicity may not be distinguishable by end point because of the overlap of etiology and manifested effects. Although the mechanism of this interaction is as yet unclear, it is not necessary to know it in order to identify critical targets of toxicity or evaluate the dose-response relationship

    We can all be confident in one certainty. As with every government acquisition program, by the time the end product is fully fielded, it is outdated/obsolete, and modifications will have already begun ensuring multiple variants will be in play.
