The OMEGA 9K will handle 300blk supers. That's really the only advantage over the Octane series IMHO. It's a sealed can (so no lead or 22lr through it).
Unless OAL is the biggest concern, the Omega 9k gets pretty crappy db ratings. I personally went with the Octane 45K for a short length pistol/sub gun can. I would also wait another 2 weeks and see if SiCo releases an Octane/Osprey 9K at shot show. That would be really tempting.
