Browning BLR '81 Optic Recommendation

[VetteVert]

I just picked up a BLR '81 in 7mm mag. I want to use it this deer season, so I need a scope on the quick. At this time I cannot afford to spend a lot (and I know the price for high end optics is well deserved, I just don't haven't allotted for it right now). Around $250 max. I am not familiar with this gun, so I don't know what size scope will fit (a 40mm? 50mm? Reticle, not tube...). Also, since i need it yesterday, it will have to come from somewhere local. To me, that means local gun shop (smallish) or Wally World.

Suggestions?

THANKS!!
