    Is there much difference between regular Ball .223 and the SS109 ammo? Got an oportunity to get a case of SS109 for a good price.

    "Ball" usually refers to the M193 round with a 55gr FMJ-BT bullet with cannelure. A standard round for AR-15/M-16's with 1:12 barrels.

    The military has moved to the M885 round which uses a 62 gr bullet. Still a FMJ-BT w/c bullet but it also includes a steel "penetrator" in it's construction. It was added to assist in penetration of heavy clothing and other barriers. It is NOT considered Armor Piercing like the old AP ammo of old that had a tungsten steel pin in it. It's merely to add a stronger part to the bullet that doesn't fragment like lead when it hits a barrier.

    If your rifle has a slow twist 1:12, it may not be as accurate. If 1:9, 1:8, or 1:7 then it's fine. Just re-zero and have fun.
