My Sabre Defence is stamped 5.56, can I still shoot .223? what are the advantages/disadvantages of either/or?

Answer 1

You should fire 5.56 however you can shoot .223 in the weapon if you must. The main disadvantage to using the .223 may be cartridge mis-ejecting or getting stuck.

5.56 is a slightly tighter tolerance than .223.

Answer 2

That depends on the rifle. My buddies M&P15 (M-4) can accept both. I think a 5.56 can accept .223 but not vice versa. DON'T quote me though, I am not sure. Call the dealer and ask.

Chris is not quite right. They are slightly different rounds.
"The primary difference between .223 Remington and 5.56 x 45 mm is that .223 is loaded to lower pressures and velocities compared to 5.56 mm. .223 Remington ammunition can be safely fired in a 5.56 mm chambered gun, but the reverse can be an unsafe combination. The additional pressure created by 5.56 mm ammo will frequently cause over-pressure problems such as difficult extraction, flowing brass, or popped primers, but in extreme cases, could damage or destroy the rifle. Chambers cut to .223 Remington specifications have a shorter leade (throat) area as well as slightly shorter headspace dimensions compared to 5.56 mm "military" chamber specs, which contributes to the pressure issues."

Answer 3

Yes, you can still shoot .223. The 5.56 nato round and the .223 remington are the same size. The only difference is the 5.56 round is loaded to a higher pressure.

Answer 4

It is the same round. 5.56mm is .223 caliber. The mm is just used because it is NATOs designation since Europe is on the meteric system.

Answer 5

.223 is simply the American measurement. It's the same round.

Answer 6

advantages-EXTREMEMLY accurate for a rifle

disadvantages-not as much stopping power as a .308


but i sort of dont get your question, .223 is the same as 5.56mm

Answer 7

it is the same round one is just the military name while the other one is the civilian name.

Just as a 308 round is a 7.62 round.
