And you can drop down the magnification a bit off maximum if your given load is below 2,800fps and still have the dots jive at 300,400 with a 200-ish zero. My 18" 6.5CM needs to be set at 10.5X instead of 12X due to velocity. The kid's 7mm-08 needed 7X instead of 9X with a slightly reduced load. Was easy to calculate with JBM before verifying at the range.
