Having only SFP BDC reticles so far it does not appear that FFP would be of benefit.  The only problem I can see is that limited to one magnification, but with the mirage maxing out the scope at 14X or so that keeps the scope cost down and really don't need for range estimation since have a laser range finder which mostly works.  Am I missing something?Sharp Shooter

A ffp mil-mil will work very well to adjust your shots for wind and drop. No matter where the power setting is, the reticle mils will maintain the same spacing. With a SSP the spacing changes with the power setting.

I'm a big fan of FFP scopes, but this is one time I'd say an SFP would be as good or better. Like you I just can't see ranging on something that size at long distances with anything but an LRF. And it seems unlikely that you'd be on anything but 14X. But if you did think you were going to use lower magnification then you could use the reticle at any power (like 3_tens said) to correct on follow-up shots. Now, that's provided you're able to keep the target in view through the reticle during the shot so you see the impact.

I prefer SFP for prairie dogs.  First, it's dang near impossible to range a PD using the reticle because they're too small and have too much variation in size relative to their full grown size, so minor errors in size can translate into major range estimation errors.  I use a laser rangefinder and take readings of landmarks around me, then estimate the intermediate distances relative to those landmarks.  Once the shooting starts, you quickly get the exact range dialed in anyway.  Second, a PD becomes a very small target at extended range and you frequently only have their heads peeking from behind mounds, so you really need a very fine reticle.  Third, most of the time, you'll be shooting in full daylight conditions where a thin reticle isn't a handicap.  Fourth, you'll be spotting your misses, so you'll fairly quickly get the exact distances dialed-in and after a couple hours of shooting, you'll become pretty proficient at estimating range based on proximity to previous hits.  Besides, there's no penalty for misses on a prairie rat town other than the ribbing you take from your buddies, who'll also be missing a shot every now and then themselves.  Due to the difficulty in judging distance on featureless, flat prairie, and the sheer volume of shooting you'll be doing, misses are just part of the game.
 
This doesn't mean a FFP reticle won't work; I just think it's a bit of a handicap for this type of shooting.  It all depends on reticle design, specifically how thick the business portion of the reticle is at the magnification you're using.
 
Just my thoughts from someone who does a lot of PD shooting.  Opinions undoubtedly vary.
 
Enjoy!

My set up is a 22/250 topped by a Leup VX111 with the varmint hunter's reticle.  Since SFP the power ring is to be adjusted to 14X which takes care, as much as possible the mirage, and the variation of the reticle lines are better for small targets as they thin out.  So much for newbies now to my question;  is there a top end scope with my desired features?  No need for big objective as no low light requirements, or fat tubes as will use BDC reticle, or illumination, but would like FL (fluorite glass) or APO for best color rendition.  Help! Basketball

Lots of top end scopes, but the best color rendition on prairie dongs, has got to be tongue in cheek. The best rendition is using Leupold alumunia filters which filters for the red range in the pelts, and makes them stand out, (and rock chucks) when hidden in grass etc. As to large objective, its not really a low light problem but getting max. exit pupil and the highest magnification that will allow. FL would give best all around (full spectrum) color performance of course. Biggest problem I have with 22-250 and swifts is barrel mirage at high powers. SFP works best, as FFP reticles usually get to large in the higher ranges. The FL diavari Zeiss would certainly be on your list.
Its not that hard to re-calibrate your sfp to a lower power if mirage or other factors are more the controls in your shooting. Aiming corrections can be done using the reticle in sfp as well as ffp, it depend more on the reticle than anything. (Hmm, anyone know of a ffp with a ballistic reticle in it?).

Was thinking of using what ever it get on my 6mmBR as way less barrel heat.  Of course the 22/250 is a repeater and the 6mmBR is a single shot.  Just moved to Las Vegas and at 11:30 AM it's 109, so there won't be much mid day shooting for this buckaroo.  Just got a dealer offer on the Minox 3-15x and 4-20x and the price is so good it's a real temptation but the reviews are iffy.  Anyone have this scope and an opinion?

I own the Minox 4-20 with BDC,I only shoot out to 400yds so I don't know if my evaluation helps.The glass is terrific,I like it a lttle better than my Conquest.Turrets are fine well made & great CS.
 
One of the things to consider between the 2 Minox's is the 4-20 is 1/8 MOA while the 3-15 is 1/4 MOA.
 
As far as FL glass goes, my Zeiss 4-16 FL is about as good as glass can get today,but you are going to pay big bucks for the SOTA glass[$1800 difference between the Minox & the Zeiss]is it worth it ? To me yes even though I'm only going out to 400 yds,but I'm 64 & my eyes seem to be missing alot in the woods compared to when I was a young 50 [:}
 
You can't go wrong with the Minox nor could you go wrong with a Trijicon,Conquest or many of the Swaro's on sale.If you are staying at a fix sight why not a SS 16 or 20X.
 
Good hunting at your new home & let us know how you made out,hope this helped.

I have ~ 50 scopes that are SFP and ~ 2 that are FFP.

One of the FFP is 2x10.
I have good vision, but on 2x, the reticle gets so small, not even can it not be  used for elevation, windage, or ranging, is cannot be found without a lot of effort.

Leupold 8.5x25x 50 Is what I have and it is pretty nice in my opinion.  I think they make one that goes to 14, I like more power, since my eyes are getting bad lol.    Mine has the varmint reticle in it, I shot a big at 565 yrds with it.  Although, it took me 4 shots to do it, since it was the first time using it, I thought that was petty cool.

I also prefer SFP especially when using mil-dot. I have the 6-18x Nikon Buckmasters mil-dot on my 17 Fireball XP-100, and get occasional 1st shot connections at ~500 yds. I use the optic at 18x all the time where the dot to dot spacing becomes 2.3 MOA instead of mil-cald. power of 12 (3.44MOA)--better for windage reference, IMO. The dot itself subtends 67% less too at ~.5 SMOA instead of ~.75.
