I have a chance to pick up a used NF 5-22x with NP-R1 reticle for about the same price as a SWFA SS HD 5-20x50 Tactical brand new! Does anyone have one of these? Both have great reviews.
VX6 are right at $1,000 at Cabelas. I do want target turrets and matching turrets and reticles, preferably MRAD. The SWFA is $1300 and the NF is $1800 (new).
The issue with 2nd focal plane scopes for long range is that the 2nd FP will obscure more of the target since the reticle is magnified as well. Also if your using a mil-dot reticle then it will only be a true mil at a certain magnification (usually max) and can easily lead to a bad DOPE, range estimation, and add a large difficulty to target recognition. However a 1st FP will be the same size at any mag setting and will always be a true Mil measurement.
These are problems for guys stretching it out past 600 yards though, a 2nd FP can get it done you just have to really pay attention and be aware of their limitations.
