As I mentioned in another thread, I recently got a very good deal on a Nightforce 2.5-10x24. It has the NP-1 reticle and right now, I'm just not all about sinking another $300 into this scope for a reticle change (it wouldn't be a very good deal anymore if I did that). I plan to shoot the NP-1 for awhile and see how I like it.
As I understand the reticle detail chart below, the thin crosshair substends 5MOA in each direction @ 10X magnification:

I've got two trajectory charts generated by the Android Shooter APP for a 75gr Black Hills OTM .223 match round fired from my 16" DD CHF barrel.
100yd ZERO:

As I'm looking at this, I'm trying to generate some roughly useful hold points to work with this reticle. It looks to me like the following should work:
Zero the upper tip of the vertical crosshair for 200yds.
The intersection (center) of the crosshairs is my 350yd hold.
Where the vertical crosshair meets the thicker bar is my 500yd hold.
I realize that these aren't super precise. If that's required, I'll dial, but it seems that using these 3 points of reference, I should be able to get "hits" on a 12" target out to 500yds pretty quickly. Again, after that I'll have to dial.
I definitely intent to check all of this at range to confirm, but wanted to see if I'm thinking correctly before I start flinging bullets into oblivion.
I don't see a way to make a 100yd zero as effective, but please advise if you do.
Thanks!
