  1. I think the bigger point is that they will stay cool in a very hot barrel without cooking off. Barrel heat matters less if that can't happen and you're using a weapon with a quick change barrel

  2.  @minhducnguyen9276  These rounds use a steel base, and the bullet is exactly like current M855 A1 and M80A1 EPRs-. Steel oentrator, copper rod core, and reverse drawn jacket. No lead at all.

  3. In the active duty, we teach press and pull, to make sure it clicked in. I don't think he received a lot of training

  4. One of the selling points of the ammo is that you can pick it up with a magnet and the manufacturer can recycle it

  5. The chamber stays cool

  6.  @jackspade5316  Still care about them, but in a sustained fight machine guns rotate barrels so they don't burn them out. Most rifles can't do that

  7. I would never choose this over an M27 or an AK 12

  8.  @phairecouchpotato3912  No, it's because I understand modern combat and think it's a terrible idea to go back to battle rifles like its 1957. At 300 or less, a squad armed with these would get crushed by one with AK12s And this round isn't all that powerful. 135 grains, 3200 fps from a 20" barrel? That's only 100 fps faster than the current 130 grain 7.62 M80A1. That's what? Maybe 10% more powerful than what we already have.

  9. Why would you drop it? It drops into your support hand

  10. It can be picked up with a magnet

  11.  @dd11111  These rounds have steel bases, meaning they can be picked up with a magnet, unlike the current ammo. Also, the cases are 100% recyclable.

  12.  @dd11111  Or, maybe this- they are developing using a plastic that doesn't melt. I get what you mean, that the designers should make sure the ammo isn't toxic and won't melt. According to the manufacturer, they say they've already thought of that. The chamber remains cool long after conventional ammo has already cooked off. Where would the cartridge melt? The chamber is cool to touch after a 100 round belt when fired in that M240.

  13. The math there is wrong, though. It's just 30% lighter than a conventionally cased round of similar power. The M80A1 7.62 130 grain bullet is fired at 2970 ft/sec from a 16.5" barrel. It also weighs 24 grams. This 6.8 round is 30% lighter with a 135 grain bullet with a similar velocity. That means it's about 17 grams. The current M855A1 5.56 62 grain bullet is fired at 3000 ft/sec from a 14.5" barrel. It weighs 12 grams. That means this 6.8 round is 40 percent HEAVIER than 5.56. Replacing 5.56 with this would result in soldiers having 40 percent less ammo (210 round base load vs. 126 rounds) for the sane weight.
