I don't have an Omega but I have a Black Diamond XR which is the same barrel more or less. Mine is scoped just so you know. I have only had mine a short time. Off shooting sticks at 50 yards, shooting .44 caliber 250 grain T/C shockwaves this rifle will make a large hole. I was shooting 100 grains of loose Triple Se7en powder. Actually other then powerbelts, this rifle shoots almost anything really well.....
