6.5 Grendel VS 300 AAC?

[JASmith]

I have been looking at the numbers and the AAC shoots a 125 grain 7.62 projectile at 2250 FPS producing 1405 foot ponds out of a 16 inch barrel while the Grendel shoots a 123 grain at 2650 FPS producing 1917 foot pounds from a 24 inch barrel.

To me that seems that if I am using the Grendel in a 16 inch barrel that I am going to be getting about the same performance from either round. Dose that seem to be the case to any one else?

Alexander Arms (http://www.alexanderarms.com/) has a downloadable sheet of ballistics for a variety of barrel lengths. Their sheet lists the 123 gr Scenar as having a muzzle velocity of 2480 ft/sec from a 16" barrel.

And yes, Drifter has it right -- Your 123 Grendel bullet starting 200 ft/sec faster will outshine the 125 gr 7.62 projectile in just about any category you can think of! (Except for cost of ammo!)
