If you are only shooting 300 yards, a BDC is pretty silly. Turrets are also a waste for that distance.
You can pretty easily tune in to a 300 yard, or very close to it, MPBR with most typical coyote rounds.
Spend the money on good glass, not gimmick turrets and reticles you will never use.
Leupold VX-2 3-9X will easily fulfill your needs at the price you set.
