This bit of news may or may not gladden the hearts of Marines everywhere; The ammo you all carry and load is destined to become lighter, thanks to modern technology.<\/p>\n
For example:<\/p>\n
One of the first polymer case ammunition rounds for wide production in the Marine Corps will be for its heavy duty machine gun, the venerable M2 .50 caliber Browning Machine Gun.<\/p>\n
The Marine Corps recently announced its intent to sole source a company to build polymer casings for .50 caliber ammunition, the largest direct fire, bullet projectile in the ground combat arsenal and a mainstay of\u00a0machine gunning<\/a>\u00a0for nearly a century. \u2013 Article.<\/p>\n According to the article, the lightening agent will be a polymer casing instead of brass, which does eliminated a considerable load of gross weight.<\/p>\n https:\/\/www.marinecorpstimes.com\/news\/your-marine-corps\/2019\/04\/02\/ammo-for-the-marine-corps-50-caliber-is-getting-a-whole-lot-lighter\/<\/a><\/p>\n Per the following article from a year ago, when this was proposed, it was a proposal to take up to 20 pounds off the weight of a belt of .50 cal ammo.<\/p>\n https:\/\/www.marinecorpstimes.com\/news\/your-marine-corps\/2018\/05\/07\/this-move-could-shave-20-pounds-off-a-belt-of-50-cal-ammo\/<\/a><\/p>\n However, the one thing they don\u2019t tell you is that you\u2019ll just be carrying more. Ammo. Instead of 100 rounds in a box, you\u2019ll get 150. The gross weight will be the same, but you\u2019ll have more volume to drag with you. I believe that there are advantages and disadvantages to this idea, and the munitions themselves are being tested, but polymer? Isn\u2019t that PLASTIC?????<\/p>\n In addition, a 5.56mm round is under development and testing for urban warfare for Marines.<\/p>\n
