Cool round but not really good for much other than knocking down drugged up aggressors in Mogadishu. I'll stick with my .308's if the 5.56 isn't getting the job done.
I've had a .458 socom for quite a few years it's an awesome gun but trust me you won't shoot it very much when ammo is $40 for 20 rnds. Also got a .50 Beowulf that's a fantastic shooter.
