6mm ARC

[biodsl]

I’m really wondering why everyone is so excited. It’s a Grendel light.

BTF said it best; the 6.5 Grendel is a hunting round that target shoots, the 6 ARC is a target round that hunts. Bill A. developed the Grendel first and foremost as an AR round for hunting whitetails. The fact that it has long range potential is almost a side benefit.

The 6 ARC was developed specifically as a designated marksman round in the AR. The fact that it stays supersonic at 1,000 in standard pressure is super cool. I have my doubts that the cartridge will ever be as versatile as the Grendel. Bullet selection in 6.5mm is too deep. Others have concerns about the capability of .243 projectiles:

"However, the .243 Winchester has limitations when used to hunt deer and other Class 2 game. The main limitation being the .243 bore size restricts the maximum weight of hunting bullets to about 105 grains. The .243 Winchester cartridge somewhat compensates for the bullet weight limitation by driving its bullets at high velocity."

I might wind up with a 6 ARC at some point, probably in a bolt gun. I'm in no rush though.
