After shooting countless Powerbelts and other types and stles of bullets; my Omega shoots quarter sized shot groups at 100 yards with:

90 grains T777 -and- 250 grain Precision Rifle QT Spitzers

I'm going to try the 250 grain Keith Nose hollow points from them next.

Go to www.prbullet.com and check them out. They know their bullets and what will work with your Omega.

Kindest Regards,
