Not sure how much research you’ve done, but I don’t see FFP being majorly beneficial for modern hunting.
To my knowledge, they were developed when the military was using the reticle hash marks for ranging targets (humans). With FFP, the distance between the marks would remain consistent, regardless of magnification. 2’ is 2’, the width of an average man’s shoulders, look at what power you’re on, that’s how far away he is. Now dial or hold over and shoot.
The advent of inexpensive and reliable handheld rangefinders means nobody really has to range with their scope any more. I can really only see using it as a “check” if your rangefinder gives you a number that seems absurd.
With a SFP scope, the mil or MOA hash marks are only accurate at max power (typically). On a 3-9 scope shooting far enough to hold over, you’re likely to be zoomed in all the way anyhow, so it’s no big deal.
Now that we have 3-18, 4-16 etc scopes becoming more popular, you might not want to shoot at max power much, but most of them now come with ballistic turrets. If you have to hold over with a snap shot, holding on the spine or slightly above the animal is likely “good enough” if you know your drops, and faster than counting hash marks.
Wind holds would be a plus for FFP, if you have the experience to read it correctly and calculate the right windage. If you’re just holding a little left or right, I don’t see it mattering. If you miss and can see a bullet impact near a hash mark, just hold that on target, regardless of what the math works out to be.
The downside to FFP is the reticle thickness increases with magnification. At the low end it might be almost impossible to see in dim conditions, and at high power it may grow enough to completely cover a groundhog at 600 yards.
That is the opposite of what you want as a hunter, IMO. I prefer a heavy reticle when in dark timber making 25 yard shots at animals running by, using low power obviously, and a thin reticle when taking shots at small targets at long range, zoomed all the way in.
So my answer is the tactical stuff doesn’t always transfer well. A sniper engaging someone up close is likely to just use their handgun, if their spotter or other team member doesn’t handle it first.
