Nevermind the yahoos with the 8-20x56 ballistic tactical scopes on their 300 RUMs. I see them at the shooting range all the time; they don't know anything about optics, rifles, or hunting, and they can't shoot their own rifles - sometimes not even from the concrete benches, let alone from field positions.
Clear optics with sharp view in low light are more important than magnification; wide field of view is more important than magnification; a reticule and that is clearly visible in low light is more important than magnification; a scope and a reticule that allow you to see and aim in the shadows against sunlight at sunset and sunrise is more important than magnification; good optics is more important than cheesy lighted reticules and magnification.
I hunt with 2x, 2.5x and 3x, the lowest settings on my scopes. I use 5x-8x when i sight in or check zero, just because i like the tiny groups. I shoot clays on the berm at 200 and 250 yards all the time, almost every week, with 2.5x.
You made the right choice. If your scope has decent optics, you have what you need. Try aiming with both eyes open at 2.5x, it will allow you to shoot faster and better. If the rifle does not recoil too much, you might be able to see and call your hits.
