A post with more information on the Oehler 88 at 2 miles would generate a lot of interest. Details on the downrange target and some sample data would really be appreciated.
In one of the papers on the website, Oehler wrote that under 1K yards, it doesn't really matter if you use G1 or G7 as the BC model. I was surprised by that, so I checked it by comparing range cards generated with each model. With the advent of CDMs, I added those to the mix as well. This is what it looks like for the OPs ballistics.
I started with the values in AB Analytics. Then I trued the G1 value to give the same drop as the G7 at the OPs last target. Looks like Oehler had a point. G7, CDM, trued G1 are on top of each other out to the last target. I also fit a straight line. There are at least of a couple versions of this out there. It's basically a mnemonic trick to avoid memorizing ballistic tables. You have to multiply and add in public and under stress, but it can work pretty well out to 6-800 yards with suitable cartridges.
Zooming in on just the errors, these are the differences at each range between the methods in the legend and a G7 range card.
It's not that G1, G7, CDM, or 4Dof don't give different results, it's that 1300 yards isn't enough range that they become significant. This graph also has a curve where the G1 was trued at 4K yards which is the last value in my template. This is intended to demonstrate that no, G1 and G7 are not the same.

What Optic Are YOU Running?

I run an ATACR 7-35 MIL-XT on my T1X in a KRG chassis.
I swapped to a Razor 3 briefly, but didn't like the parallax wheel, and especially not the turrets. I had one lock on my during a stage and they don't unlock very fast at all. The ATACR just does what I want it to, and I don't notice anything about it. The parallax wheel is the just right, the turrets with a turret tape are great. It's a bit overkill magnification wise, but it's not bad. It's very clear at 12x - 20x where I'm shooting at anyways.
Above all, I like the reticle. My preferred reticles are JVCR, MIL-XT/C, PR2, SCR2 variants. Leupold and USO's FDN line don't have low enough parallax, and Burris doesn't have my trust mechanically like the NF and USO has. The MK4 has low enough parallax, but I don't like to run non-flagship optics, as I believe the flagship optics of a given company will have better support, and be more reliable.
March's new FML-WBR looks incredible too. If I had that budget right now, I'd be looking at that new March 5-42.

Former Housing Official: U.S. Government Has Built a $21 TRILLION Underground City for the Wealthy and Powerful to Live If a "Near-Extinction Event" Occurs (VIDEO) | The Gateway Pundit | by Cullen Linebarger
A former housing official recently made a shocking allegation that, if true, will prove the most wasteful and arguably sinister government expenditure of all.www.thegatewaypundit.com
I am going to call bullshit, two years and who funded her "research"?
Besides, unless 95% of the people here were there, I'd just as soon be rotting on the surface than be trapped underground with the society we have morphed into
