5.56 vs .223
I hoping yall can settle a debate between me and a friend...
I'm sayin that you're not supposed to fire 5.56 in a rifle chambered in .223 but you can fire .223 in one chambered in 5.56. The reason being that the 5.56 has more powder and runs at higher pressures.
He is saying that the 5.56 has a thicker case and therefore should hold less powder.
Isn't it true that you can fire a 7.62x51 in a .308, but you shouldn't fire a .308 in a 7.62x51?
Thanks in advance
