I like both first and second plane scopes. Each has its benefits. On a SFP scope you can use the changing reticle size to customize your BDC reticle for loads and ranges by turning the power up or down.
On FFP scopes, as stated earlier, you can calculate range at any power. What most have not realized is that the reticle does not cover more of the target at higher magnification, it always subtends the same amount. The reticle grows with the target thus appearing to cover more of it. It does however cover a larger portion of the target as the target gets further away.
A SFP scope reticle shrinks relative to the target as power is increased, so it subtends less of the target at higher magnification.
You can't fix stupid....however ignorance can be cured through education!
