I'm shopping for a rifle that I can use mainly for hunting wild hogs. I'm interested in an AR-10 format because I have several bolt action rifles and want a semi-auto. I also want to hunt big game legally in Colorado with the same firearm. I've seen one listed as an M1A SOCOM 16 CQB .308 Win/7.62x51mm... I'm wondering if this means it fires either .308 Win or 7.62x51 mm -- whichever I want to use, implying they are identical. Is that right?
Answer:
Hello Cleve! Totally your call if you want to hunt deer with a M16 SOCOM 16. Me, personally? I'd want a longer barrel than 16", just so I can squeeze a little more juice out of the 308, both distance and stopping power wise. That said, the 308 Win and 7.62x51 aren't identical to one another. They have different pressure capacity, case sizing, and chamber dimensions. The 308 Win is the higher-powered round. *That* said, a 308 Win rifle (such as the M1A) can also safely fire 7.62x51 ammo, because the two cartridges, despite not being identical, are extremely similar. If you see a rifle listed as ".308 Win/7.62x51mm," that's just means it's a 308, and can therefore fire 7.62x51 too. Hope that helps!
