FFP and SFP scopes explained

JoeWayneRhea,
Thank you for all of the scope info that you post.
There is one part of the ATHLON video that is a little misleading. The speaker says:
Second focal plane reticle:
"That means the you can only use the reticle subtension for ranging or holding over on a specifc power."
That is not true. You can use the SFP reticle for ranging or holding over on ANY specific power (magnification). As long as you know what the subtension is at the specific power that you are using, it will be accurate. I'm fine with MOA or Milliradian, or anything in between. As long as the user knows what the subtension is, it works fine. I use "MIL" reticles extensively in competition for both holdover and ranging. But I never use them as milliradians. I choose the magnifications that I intend to use for shooting and measure the subtensions at those specific magnifications. For my SFP scopes, the two most common settings are min and max. That gives me two solid stops where subtensions are accurate per their expected values.
I like that the SFP scopes give a consistent reticle size so that it is easy on the eye to read whether they at low or high magnification.
I'm finally getting into FFP scopes. The FFP reticle is not too useful at very low magnification, as the reticle gets way too fine to see easily or read accurately. The advantage of the FFP is that I will be able to use it at 16x for Hunter Division field target, and then switch to Open Division Field target with 24x, and use the same dope sheet. I'm withholding judgment on my preferences of SFP vs FFP until I get a chance to use the FFP scope some more.

Thanks man, I mainly just shoot off my bench and plink so for me a fixed power or SFP makes sense .
But a really badass FFP is hard to pass up
