So quick question for everyone, I was doing some reading / research today and I found that the US Army M24 sniper rifle (Remington 700 Long Action) was chosen to allow the Army to use both 30-06 or 308 is this correct that a Remington 700 chambered in 30-06 can also fire 308 rounds I know a 308 / 7.62x51 is essentially a shortened 30-06 case they are both the exact same 30cal projectile. 

No, No, No....My understanding is the rifles when ordered were supposed to be 30-06 but there was not enough 30-06 Match ammo available for use in the future.

 

So during production they were chambered 7.62X51 due to better ammo availability. The same round as the M-14.

 

Thus M24's were chambered in 7.62X51 on a long action.

 

BTW 7.62X51(308 Win) and 30-06 are by no means interchangeable.

Ok that is kind of what I thought they meant they simply took a 308 chambered barrel and put it on a long action receiver. This might be kind of cool to do as it would let you essentially use any 700 barrel you want regardless of it being a short or long action.
