The newest "Arms And Ammo" episode has a segment where a Special Ops guy says that a 300 yard zero has it's advantages. They use the 6.5 Creedmore as an example.
I'm in the process of trying this out.
Opinions.
36 yard the same as 300 yard, correct? i do mine at 36 yards.

Its my understanding that you zero at 100 yards or meters. Then work the math and recticle adjustments from there. I mean that's what the really big marked turret knows are for right?
Safe to say these holds are using a mil dot reticle?

True....Mils are a measure of angle, just like MoA (minutes of angle).
Not Really. A mil is derived from a circle, and the exact dimensions and geometric relationships of the circle are in no way related to the metric system. Here is how it actually works:It's just an SI (metric) measure instead of an English one.
True.You can calculate holdover / holdunder in either system. Some reticles are set up with mildots (i.e. they measure in mils, or miliradians), and some are in MoA or other measures. Some have BDCs, or bullet drop compensators, which are generally set up for a specific load out of a specific barrel length and a specific zeroing distance. Then you just range your target and put the appropriate point in the reticle on it and shoot.
If you know what your'e doing you can calculate a hold no matter which type of reticle you have.
Philosophies being what they are, the overruling concept is "The Right Way, The Wrong Way, and The Army Way..."Post #9 and post #10 lay out the dueling philosophies back to back . And my take is ... not exactly either .
I would slightly modify " zero AT your most likely distance " to " zero so as to not require meaningful hold under at most likely distances " .
For Me ( and what I recommend ) is impacting no more 1.5in high . For deer sized ( includes upright 100-200lb critters ) , 1.5in can be effectively disregard , but meaningfully extends the farther point blank - ish range .
My disagreement with the maximum point blank theory is its putting equal value upon holding under at more frequent distances, and hold over at longer distances . I despise hold unders , and accept reasonable hold overs .
