Nice because you can also clearly see your hits as you adjust. This is specifically for 55-gr FMJ (assuming X193), but it's worked pretty well for me with .55-gr 223 as well.
 
I love those targets and use them a lot. My local outdoor range only goes out to 55 yds, so the adjusted ones really help.
 
What's nice is as the video pointed out, out to 300 yds you're pretty much within the size of a CD, so for combat you're good. My thing is when shooting close range or in tactical/competition stage I have to remember my holdover especially in smaller target areas or head shots at 'speed'. Circle-Dot reticles can help but unless in a large-window dot sight like an Eotech, I find them a bit too busy and prefer just the dot. So for say a head-shot in the 'A-zone', got remember to hold on the top of the forehead.
 
I think it comes into play more for actual 'operators' or LE SWAT that may have to take a head shot in a live cover or hostage situation within room distance. But then a lot of competition also simulates that with no-shoot targets obscuring all but a small part of the intended target et al. It even comes into play with pistol red dots as there's still an offset from barrel and some shooters tend to yank a bit as they're shooting 'at speed'. But yeah a 2.5" or so offset from bore can be big at CQB distances. Just takes some practice to get used to holding a bit high within 15 yard or so.

My pistol-caliber-carbines I usually zero at around 45-0 feet because that's around the usual distance for steel/plate targets and about as far as it gets in CQG competition stages. Offset isn't as big up close as with rifle.
 
Also keep in mind that the target posted for 25yds adjusted for 36yd is for a typical Eotech or Red Dot with an absolute cowitness to lower-1/3rd mount height (like 1.41 to 1.6x" above rail). If you use like a 1.91" high mount or have your red dot way up on top of your scope like....

...it's going to change the impacts a bit, obviously.


On my gaming rifle that has a 1-6x scope, I have a 35Ëš offset mount like this....

...so height over bore is still within that range.
 
Yup. My holds are ingrained. Given the degradation of accuracy just from age, probably shouldn’t create uncertainty by changing my zero.
Yeah if it's 'in your blood' already, you're probably good anyway. 36 just seems more of a 'cushion', or the reverse if you will for 'quick and dirty'.
 
My 1-6x scope has the ACSS reticle, which works great. My first 3-gun match, my best stage actually had plates out at 300 yds and I was sitting them at a good pace 1 for 1. The holdover marks were spot-on....

Yes Strike Eagle does. I bought one as an affordable entry scope as I was getting into 3-gun. Switched out for a Primary Arms 1-6x because I liked the ACSS reticle a bit better.

And yeah, as illustrated in pics I posted earlier, it's gauged for a 100 yd zero.

Why 36 yards ?
Check the following posts, pics and vids illustrate how the overall bullet-drop spread between 50 and 300 yds is minimal in a center-mass area point-of-aim compared to others. So it makes an ideal 'combat zero' for a red dot or Eotech sight.
