6.5 Grendel
The original long-range AR-15 cartridge — still a bargain deer-and-steel setup, with 6mm ARC as the newer sibling it has to share the room with.

History
Bill Alexander introduced the 6.5 Grendel in 2003, built off the .220 Russian/PPC case to push efficient 6.5mm bullets from the AR-15. It gave the small-frame AR real 800-yard capability years before that was fashionable. Once the trademark opened up, it grew a durable following for deer hunting and budget long-range gas guns.
