There is a pretty extensive list of excellent scopes under $600 that fit your needs.
I've owned some scopes that fit your needs that cost me less than a third of that.
You are saying that a Leupold VXIII was inferior to a Tasco ?
No suggestion I make will be adequate then..........
I have a couple of Burris FFIIs mounted on bigger more powerful guns than your 06 and they have lasted many years and never require re-adjustment. Cost me $200 tops
