If it is loaded by Santa Barbara, it should be very accurate ammo. In fact, this is one of the most accurate SS109 loads you can buy. I just got my new SG Shooter's catalog today as well and saw this ammo, but I can't confirm it's Santa Barbara. You might give em a ring and ask before ordering. FWIW, I have also heard a few others say it doesn't seem to perform as well against steel as US and Israeli M855. Again, I am not telling this to be the literal truth as I have no idea, but I have heard this mentioned. Nevertheless, if it is SB it should make some very nice target/plinking loads and is cheap.
