The TEZ works good in mine too as does the MZ Spitfire 285. I spend most of my time shooting the .454 .452 300 deep curl at around 30.00 for 50 w/ shipping. The 300 scorpion PT Gold you may find to shoot nicely out of your Omega w/ the crush rib sabot. I have not had the chance to harvest anything w/ any of these but I feel confident they will do nicely if the opertunity presents itself. The guys here have a lot of hunting experience so I follow their plan. Sometimes it's ok to be a copy cat.
