asianhunter: I know you are new to this sport as you said so in another site post. I have the same rifle stainless Omega synthetic stock. I think you will find that you do not need to load anything near those maximum loads to get the job done. Unless you are planning on shots exceeding 150 yards anything over 100gr. of any of the powders is just overkill. I hunt elk and consistently shoot completely through the chest (as long as bone is missed) with 90 gr. of Black Mag'3 and 300gr. SST bullets. I did the same with 90gr. Pyrodex and a 295gr. Powerbelt aerotip. These shots were at less than 100 yards and the elk were fair sized cows. Still way bigger and tougher than any deer. I have had very good luck with Black Mag'3 although it is difficult to find in many areas. Most Omega owners seem to love the way it works in the Omega. Tripple Seven does not work very well in my Omega as it forms a real bad crud ring which makes second loads very difficult or impossible. I would start with Pyrodex either loose or pellets as a lot of the initial development of the Omega was done with Pyrodex from what I have been able to find out. It is also easier to find than most of the rest. It is pretty dirty but as long as you follow the normal shoot, spit patch , dry patch, reload and shoot it works just fine.
