What’s the Difference Between 6.5 Grendel & 223 Remington?
One significant difference between the 6.5 Grendel and the 223 Remington is that the 6.5 Grendel shoots in the wind easier since its bullets have a higher Ballistic coefficient. At the same time, the 223 Remington does a pretty reliable job at 100 yards because it was designed for close-quarter combat with the low recoil.
To claim that Alexander Arms created and mass-produced the 6.5 Grendel to surpass the performance of the native 5.56 mm NATO/ 223 Remington cartridges created the buzz of comparison between the native ammo vs the newer one.
With the 6.5 Grendel sporting a shorter, larger diameter case for higher powder volume while allowing space for long, streamlined, and higher ballistic coefficient (BC) bullets, is it enough to overthrow the reigning ammo for AR-15?

Remington 223 vs 6.5 Trajectory
If we were to discuss the 6.5 Grendel vs 223 Remington’s ballistics, both ammo has about the same performance past 600 yards. Their bullet drops at 600 yards are pretty comparable, too, with a drift that’s about 25% less. But then, the Grendel has over twice the retained energy even at 600 – 700-yard range, while the 223 starts to drop considerably faster. With this, the 6.5 Grendel takes its first win having a flatter trajectory over the 223 Remington ammo.

Heavier bullets mean more power and better penetration. In this category, the 6.5
Grendel takes a winning streak against the 223 Rem because not only it offers ammunition with a heavier and larger diameter but also better penetration.
Grendel also provides more power and more range than the Remington 223.
6.5 Grendel & 223 Loading Type
The 6.5 Grendel offers factory-loaded ammunition with bullets ranging from 90 to 130 grains, while the 223 Remington has bullet weights ranging from 36 – 77 gr bullets. Since the 6.5 Grendel perceptibly offers a shorter bullet but with a larger diameter case for higher powder volume, streamlined, and has a higher ballistic coefficient (BC) compared to the 223 Remington, the 6.5 Grendel takes another win.
6.5 Grendel & 223 Remington Recoil
Because of its heavier bullet weight and diameter, the velocity of the 6.5 Grendel is lower than the 223 Remington.
While the 223 is lethal for close-quarters battles, due to its low recoil, the Grendel 6.5 has double the recoil and slightly less capacity than the 223.
With this, the 223 Remington takes another win.
