I have the TC omega and sighted this gun in for several bullets. One thing that I know is that MY omega does not like conicals at all. It shoots the powerbelts well but I don't like the powerbelts.

Buffalo Bullets:
225 grain sabot/bullets...90 grains of powder, 100 yards, 3 rounds I could cover with a quarter.

Precision Rifle bullets:
215 grain sabots, 90 grain of powder, 100 yards...all rounds in the bullseye.

Precision Rifle bullets:
330 grain extreme elite sabots, 110 grains of powder, 100 yards and all bullets in the bullseye.

I decided to go with the heavier bullets and I'm glad that I did. I shot a buck at 70 yards this past year during Illinois muzzleloader season and he went all of 30 feet. Dropped him something fierce...

I feel that my omega likes the heavier rounds better...I've got to re-sight in my gun as I replaced the synthetic stock with a thumbhole laminate stock.
