Re: vortex pst ffp, or ,mark 4 ffp
I think you may be making a major decision based upon a relatively minor issue--there are bigger more important differences between the two scopes in my opinion.
The equivalent FFP MK4 with matching turrets is getting close to twice as expensive. If you get the 40% military discount it becomes a more attractive choice, but without it it's a whole lot more money. It has no illumination or zero stop. The TMR reticle is very nice in my opinion, but for hunting in the brush in low light it really could use illumination. If you don't ever do that it might not be a big deal. A zero stop is really nice, especially with only 5 Mils per turn.
Most of us have gotten along just fine for a long time without the windage being printed on the dial (or range for that matter). A quick glance at a chart taped to the stock or scope doesn't take much time, wind is pretty easy to memorize (especially in Mils), or if you really want it on the turret there are ways to get it on there. I've been making my own BDC labels for all sorts of scopes for a long time, getting something workable for wind would not be difficult.
In short, I just think there are much more important factors to consider when choosing between scopes that whether Kenton will put wind on a turret or not.
