Re: focal planes
As far as function, if you intend to range with a laser range finder and dial your solutions with turrets, go SFP with a simple med-fine crosshair(if you can get it).
If you intend to range and hold-off with reticles, go FFP, and whatever reticle you think you can do both with and still hit a small killzone.
Either way, if you're hunting, don't buy into cheap tactical wannabe junk, but focus on field functions(what you actually need).
Given that armageddon is not upon me yet(I can still buy batteries), I prefer laser ranging, dialing elevation(in 1/4moa), and holding off for wind(in inches). I prefer a med-fine crosshair like NF's CH1, that works perfect in the field for varmints. Not too small/large, and simple.
My solutions are taken from a printed off click card carried along.
I use either MK4 or NXS scopes ~25x.
My hunting guns are atleast 1/2moa cold barrel accurate(for x distance) off a Harris bipod, and I always position myself to within killzone requirements given this accuracy, or I don't take a shot.
This is not Hollywood. I get one shot per groundhog, and I can engage multiple GHs at ~30-60sec intervals with my system, provided situations support it.
I could not range groundhogs with a FFP scope. I could not even see a GH behind the reticle of FFP scopes I've looked through, much less hold-off between hashes with the target aspects GHs typically provide. Maybe that would be different if my targets were pakistanis..
