Why is the U.S. Military Switching to 6.8mm Ammo? Bigger Bang, Better Accuracy

Why is the U.S. Military Switching to 6.8mm Ammo? Bigger Bang, Better Accuracy

The most commonly used bullets

The pros and cons of both are clear

Currently transitioning to 6.8mm
 
There is a tongue-in-cheek saying, ‘If you get shot gently by a bullet, you’ll survive.’ Of course, this is a nonsensical statement, as any bullet hitting any part of the body could cause fatal injuries. Military writers will know that bullets used in rifles or machine guns, like the 9mm, have enough killing power.

So why are the representative bullets commonly used in rifles and machine guns, the 5.56mm and 7.62mm, used separately? Today, let’s look at the pros and cons of these two bullets and their alternatives.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

Better ballistics + a compromise among bullet weight, muzzle velocity, and knockdown power.

I have a 6.5 mm Swedish Mauser that was manufactured in 1900, and I swear it is the best deer hunting firearm I have ever seen.  The bullet's trajectory is extremely flat and it gets the job done.  6.8 mm is slightly better.

I use a .270 Winchester round (roughly 6.86mm) for hunting which has a similarly flat trajectory. Not quite as powerful as a .30-06, but easier to hit what you're aiming at without elevation adjustment.

"The most terrifying force of death, comes from the hands of Men who wanted to be left Alone. They try, so very hard, to mind their own business and provide for themselves and those they love. They resist every impulse to fight back, knowing the forced and permanent change of life that will come from it. They know, that the moment they fight back, their lives as they have lived them, are over. -Alexander Solzhenitsyn

I have been happy hunting deer and hogs with a 6.5x47 Lapua for several years. I have recently picked up a 6.5 Grendel, but haven't hunted yet with it.
