Ziess Conquest 6,5-20x50 A/O with #43 (mil-dot) reticle is in your price range. Excellent glass. Crisp image even on 20x. 1/8 clicks w/adjustable knobs. 3 1/2" eye relief, 1" tube.
I have one mounted on my 338-378 brevix. Easy to adjust and good in low light conditions too. Designed as a hunter, but excellent for target.
No such thing as a stupid question. What is stupid is not asking it.
