6.5 grendel is great for medium range hunting.
The 6.5 projectiles are awesome and very slippery. (high ballistic coefficients)
You can also go long range with it, easily 800 yards, some people even push 1200.
Honestly I don't think the 6.5 grendel is worth the extra money for target shooting. With the right ammo you can push a .223 out to 1000 to 1200 yards. Further than that just get a bigger gun. And the grendel needs special mags.
