Run the data through a trajectory calculator, such as the JBM Ballistics website. I think you'll find that a 6.5 123gr bullet at ~2400 to 2450 fps from a 16" barrel will have more energy and flatter trajectory versus a .30 caliber 123gr at 2250.
I think the 300 AAC might have been designed for suppressor use, and / or use with subsonic ammo, but I could be wrong.
What would be the intended use of the cartridge(s) for you?
