RE: Big groups with t7 in Omega ?
Agree with Cayugad... as I do almost every time!
777 loose works better in 100-120 grains with the Omega. That rifle seems to do better with the 45/50 black magnum plastic sabot & the blue 40/50 sabot vs the green ones because of the heat produced by 777. If you switch to pellets, stay with the Pyrodex in the Omega. Most Omegas will shot three Pyrodex pellets (150) very well... even though T/C or Hodgdon no longer recommend using that much powder.
