I got my first muzzloader this past season and it was also an Omega. Is yours a synthetic stock or the laminate thumbhole stock? Depending on your answer, there may be a thread or two by Sabotloader you might want to review (there may be some stock modification required if you are getting a synthetic).

I have had good success with the following:

• 260 gr Harvester Scorpion PT Gold bullets w/ Harvester black crush rib sabot, 90 gr BH209, CCI 209M Primer – I get 1 MOA with this setup. However, I’m going to do some more experimenting with an increase in powder charge and using the RED crush rib sabot, which is designed for use with smokeless powder (since it has a nitrocellulose base, BH209 is widely considered to be smokeless powder with the smoke added). I’ll eventually try the 300 gr PT Gold bullet when I have enough coin to do so. As far as terminal performance goes, I killed a buck at 150 yards and he only went about 10 yards and had a massive blood trail. The shot was right where I put it, too.
• Leopold Ultimate Slam 3-9x40 scope mounted on the DNZ (Dead Nutz) Game Reaper low one-piece mount/rings (HIGHLY recommend the DNZ!!)
• SpinJag loader and starter (also HIGHLY recommend those products).

I have had good success cleaning the BH209 with Hoppe’s, Gunzilla, and Blue Wonder solvents. If you use BH209, you’ll need to keep the carbon build up in your breech plug’s flash channel at bay with a 1/8” drill bit (twist by hand or use variable speed drill SLOWLY). I also use XF7 lubricant (grease) on the breech plug and I have never had any difficulty removing it.

My Omega was a bit sporadic at first, but I feel 95% confident that it was because the barrel was a little rough around the edges. I took some 0000 steel wool and wrapped it around a cleaning jag and, with the use of some solvent, did about 50 passes down the barrel. The gun has not been sporadic since. Some use JB’s bore paste to accomplish this. I just didn’t have access to any and I don’t feel the steel wood did any harm. Now, if I used steel wool all the time and the barrel, that would be different.

If your Omega’s barrel is blued, keep it clean and oiled (inside and out)…NO MATTER WHAT POWDER YOU ARE USING. Don't wait a couple days after your range session to clean it. I have found that my Omega’s barrel is EXTREMELY susceptible to rust. I have no idea if the stainless steel barrels are the same way…I would hope not. I will be applying Dyna-Bore Coat to the…you guessed it, bore, and will probably be painting the exterior of the barrel…camo, of course!!...to take care of the rust issues.
