Good post.
I actually prefer the PST reticle, but to each his own
What do you mean the PST failed the box test? If you're talking about the fact that the erector has limited travel before it starts to follow the curvature of the scope tube, then you'd be correct. But then, that's the case with all scopes, though some manufacturers prevent the erector tube from moving once it contacts the scope tube. I've done some testing with my PST 6-24 FFP, and it has a workable elevation range of 69MOA with the windage zeroed. With the windage maxed out to one wide, the usable elevation range is reduced to 22MOA. But that's after you've dialed in around 30MOA of windage. With the rifle sighted in, there is 5.75MOA of windage dialed in, and I still have 68MOA of usable elevation. I've got the scope mounted in Burris Signature rings with 0.010" inserts in front and back, and on an IOR 20MOA rail. The rifle is zeroed at 100 yards, and the scope is zeroed with 6MOA of "down" remaining, and 62MOA of usable "up" left in the elevation turret. If I dial in 10MOA of windage, then the erector assy has 58MOA of usable "up" before the erector starts to follow the arced path of the scope tube. From zero, I have 18.25MOA of usable right windage, and 21MOA of left windage. If I top out the elevation turret (62MOA of elevation dialed in- enough to get my .243AI out to 1660 yards with a 105gr Hornady HPBT at 3144fps, where I do my shooting), the erector will still allow me to dial in 11MOA of windage to the right, and 17MOA to the left. The usable left and right windage would be mechanically equal if I bothered to take the time to orient the Burris ring inserts to zero the windage without having to use the scope's erector assembly.
Then if you consider that the FFP reticle gives me another 10-30MOA of correction in any direction in addition to what the erector assy offers, it's more than enough to compensate for shooting out to 1660 yards in a 10MPH wind using only the erector (I would never do this, since I hardly ever dial windage when I have a good reticle, anyways), or beyond a mile in up to 20MPH winds if I use the reticle for a hold of 10MOA elevation and windage. If you want to use the reticle for more than 10MOA of holdover and hold off (which you can, with 30MOA of usable elevation holdover and 30MOA windage, the elevation being marked in 2MOA hash marks out to 30MOA, and the windage being in 2MOA marks out to 10MOA, and 5MOA increments beyond that out to 30MOA), then I can shoot at a mile in up to 34MPH winds (hah! I'm not expecting to hit much in these conditions!). That is plenty of elevation and windage correction for my uses, and if I need more in a FFP scope, I'm going to run a NF, S&B, March, etc.
The two PST FFP scopes that I've played with (one 6-24 and one 4-16) track and RTZ like a dream, and are very usable scopes for LR shooting. You just need to make sure that you record on your dope sheet how much usable adjustment you have in the erector before it starts to travel in an arced path. It would have been nice if Vortex has installed a "stop" in the erector assy when it hits the scope tube, rather than allowing it to travel along the arc of the scope tube, but it's not the end of the world if you measure usable travel, record it, and work within those confines. For an FFP scope costing roughly $1000-1200, I feel that you still get a lot of LR bang for your buck.
