Probably m193 out of a 20" gunSo does anyone know what load the marks are based on from the get-go?
Sorry if I'm derailing, just curious how the come-ups are marked to begin with. Is there a universal load?

I think this is right. It's still 1 moa adjustments on the wheel. Height above bore is the main factor when calculating ballistics, much more important than any other factor. There isn't even that much difference between .223 and .308 until you get way out.
I'm thinking M855, but I could be wrong.Probably m193 out of a 20" gun
I'm no expert either so take this with a grain of salt.. I understand what everyone is saying about better accuracy with longer sight radius. Geometrically speaking, I think you are correct to believe the distance between the sight will affect the standard "come ups".
I think about it like this. If your sights are an inch apart and you lower you sight 1 click ( for demonstration purposes let's say 1 click =1 inch). that would equal a whole bunch of moa (like 45 degrees.) now say your sights are 100 inches apart and you adjust that same 1 inch click. Far less moa shift. Obviously that's an extreme example but it will make a difference. At least in my semi drunk mind.... Not sure if that made any sense.
Nice! I'm curious, what are your thoughts on using the 100 yd zero or 50/200, relative to trajectory, battlesight zeroes, point blank aiming, etc? I know they aren't what is taught as doctrine, but I'm curious about your thoughts vs the standard zero methods.Lots of good questions... ^^^ I love to give a SDM M16 class, ( classroom 1st ) The base sight setting for the M16/M4 is 300m. Thats why you shoot a simulated 300m target at 25m ( appx. 82 feet.) so when you go to the pop up target range, you can hit all of your targets out to 300m. problem is, there is all most 7 inches of arch of the bullet path, that happens at at 175 meters, so most people in the army have a hart time w/ the mid range targets 150m and 200m mainly, and they pop up the most. This happens for 2 reasons, 1st the target at 25 meters was zeroed too high ( you should be low on the 25 meter target to compensate for the path of the bullet, and 2nd most people tend to aim high on the target, insted of center mass.
Anything past 300m is where you will get your come up. ( like my examples before) remember standard Suit case sights are 1moa adjustments, but there are national match suit case sights in 1/4 MOA & 1/2 MOA adjustments... this is a way long talk, and I suck at typing... Anyone want to set up a indoor class for me just LMK...

You sound a lot like one of the lead instructors at the KD. He is a big believer in BSZ and only adjusting for 400 and beyond.
@DarthVader, I will be confirming all this in the field and writing up a dope card. I'm sure there's math involved but I thought there was a "right" sight radius for the A2 rear. This is a gun site, and we don't spend near enough time talking them.
The right side knob is the windage knob, there is a way to market it when you have your 300m zero, and you can make windage calls at any distance and go back to your no wind 300m zero... Once again, hard to type, easy to explain. Not a lot of math involved w/ getting your iron sights set, just need to know your dope, for 400m, 500m and 600m. and you should be able to dial in your sights, and hit targets.
Return to zero is emphasized. Sight adjustments aren't magic, they're repeatable, and once known, you can go back and forth and know when you pick it up again, it'll hit where it's supposed to.
This is my first time trying it with an irons only AR. I've done this with scoped rifles, a garand and a M1a.
You should let me bring you to an Appleseed. If you like teaching riflery, we could help you with finding the outlet. It sounds like you have a lot to offer.
I'd go if you want to take me... I got spoiled at Ft. McCoy, get your rifle zeroed, go shoot it to 300m, or go to range 34, and depending what you had, stretch it out to 1200m meters... But I will say this my eyes have gotten bad, and need to find a Bob Jones sight if I'm going to shoot irons... If I dont wear glasses, front sight is clear, cant see the target... If I wear glasses, I can see the target, front sight is fuzzy... Sucks to be old...
