RE: I'm getting frustrated!!!
Yeah, ML is frustrating at times, isn't it? I pulled a lot of hair out in the last year trying to get the accuracy from my new SS/laminate Omega that I knew it should produce. Here's whatworked for me. I ended up using 300 grain Shockwaves in Harvester sabots over 90-110 grains of Black Mag 3. (The pattern starts to blow at 120 grains, and the recoil gets rather brutal at that level anyway.)I found full power Winchester or Remington primers,but not the Kleenbores,work best with the BM3, although Tahquamenon seems to get good accuracy from Kleenbores and BM3 (I can't). I use 50/50 91% isopropyl alcohol/windshield wiper fluid (hat tip to Tahquamenon from about a year ago on another bulletin board)to clean after every shot, and always shoot from a clean, dry bore. Result is 1.5" to 2.0", 3 shot groups at 100 yards if I do my part.
Try the loose T7. Compared to BM3, it just takes more work to get that bore consistenly clean between shots with T7. I tried to shoot from afouled bore or from a single spit patched bore, but I just couldn't get consistent patterns. A really clean bore, and the 50/50 solution, did the trick.
Are you using the T/C extended jag with the Shockwaves? Nothing blows a pattern faster than mangling the nose of the bullet as you seat the sabot as a buddy of mine found out recently. Be sure you have the right loading jag.
You don't mention a scope -- are you shooting with the original fiber optic sights? If you don't care for or can't afford a good scope, I believe Williams makes a peep sight for the Omega that might help.
Good luck, and keep at it!
