They say .223 military style... I'm thinking maybe they mean 5.56?
But you can get many rifles chambered for 5.56, and most .223 can fire 5.56 without causing damage.

Just to confuse the non engineering type's ... one imperial and the other metric .. Lotta people think for example the M-60 is a whooper machine gun .. but so is the Lee Enfield .303 .. 7.62=.303 .. or .312 in decimal is 5/16 or near enough to 8.0mm but lessor at 7.9 ..

Same size. 5.56 does however pack slightly more punch (higher peak pressure in the firing chamber), something to do with the type/amount of powder used etc. Not quite interchangeable in all applications, however studies have shown that most of the time there will be no harm swapping the two.
Edit: And the Ammo is not the same. Very similar, but definitely not the same.Last edited by huff3r on Tue Apr 30, 2013 5:10 pm, edited 1 time in total.

Close but 7.62mm = .308 cal![]()
BTW .303 is a much bigger bullet in length to a normal 7.62mm long bullet when comparing the two bullets.

.223 = 5.56mm the difference is not in the calibre but in the ammunition type. If a bullet is made for military use then its likely to have better performance and stopping power than training ammunition or other types.
