Good Mil based system with Horus or at least subtends

Depends on what kind of shooting you're going to do I guess. I shoot mostly long range stuff, but I shot a long range match this past weekend that had a barricade stage with targets as close as 255 yds. I had to dial down to about 10x to have a decent field of view, or I'd have been hunting all day for targets. This stage was also a 'No Dialing' stage, so I couldn't touch my turrets. FFP made it a breeze. Otherwise, I usually shoot on full power though.

FFP made it a breeze for you for what reason?
Im just assuming its because you (prefer) the reticle size to remain constant thruout the power range?
Would there be other reasons?

SFP keeps the reticle size constant. FFP has the reticle grow & Shrink with magnification changes; what is constant is the distance between the subtensions, regardless of it's apparent "size".

Because the reticle is accurate no matter where your magnification is set. I have a SFP PST and the reticle measurement is accurate at 24X, now if I need to dial down to 12X, such as noted for a better field of view, my measurements are now doubled, with an FFP scope it is always the same, no calculations needed. So with the SFP scope I have to calculate for the change in distance when using holdover or holdunder using the reticle. For an easy example, I'm zero'd at 100 yards, 200 yards is .6 mils, 300 yards is 1.4 mils, 400 yards is 2.4 mils, 500 yards is 3.4 and 600 yards is 4.6 mils. If I have three targets to shoot for the stage, one at 100, one at 300 and one at 600 and usually it would be 300, 100, 600 just to make it more interesting. :) Using the reticle and an FFP scope I'd dial for 300 and hold under 1.4 for the 100 yard target, and hold over 3.2 for the 600.

Now for the SFP scope mentioned above in the same scenario at 12X I'd dial for 300 and then since the reticle measurements have doubled I'd have to hold at 1.4/2 or .7 mils and 3.2/2 or 1.6 mils . Easy enough to do when you have time to figure it out. Not as easy when you have 60 seconds to put two rounds on each target in 60 seconds. And then if you do this regularly you know your dope for the distances mentioned but now you are calculating it due to the changes in magnification. At 18X it is .5, any idea what it is at 10X? :)
