[QUOTE="Mikecr, post: 543467, member: 1521"] Not accurate with terms I'm sure, but; With FFP reticle subtension is more or less fixed/constant. So it grows with the magnification. This my main disappointment with FFP, as it degrades the aiming precision I need for long range shooting. With SFP the reticle subtension decreases with magnification. Very precise. But, it's not linear. A SFP reticle does grow with magnification, just no where near the amount a FFP reticle grows. With this, I am unable to see a fine crosshair on one of my Mk4s at 8.5x, as it's just too fine. I can see it at ~12x, and perfectly at 25x. But med-fine crosshairs are atleast visible at the lowest setting while being fine enough at the highest setting. So it's easy enough predict that Leupold doesn't offer a med-fine crosshair reticle! This was provided by Premier Reticles -in the past.. It is apparently unfortunate that scope makers don't actually use their own products. They would learn so much if they did. Many don't discuss things like reticle subtension, because they don't even know what their scopes actually provide. Leupold is one of them oblivious to it. Just ask the 'custom shop', they haven't a clue. Go to March & ask.. They don't know. Now get into diopter values,, woosh,,, right over their heads! I have an issue with NF there.. [/QUOTE]
