Thank you Form for sharing your MIL based methods. I appreciate anyone willing to share things that work for them (and in this case lots of people) in the field.

I am pretty invested in MOA from a scope ($$$), experience, and hunting party perspective. The group I hunt with talks MOA and when sighting shots we speak MOA. So as much as I understand the simplicity of a base 10 angle angle system, I have some inertia that keeps me thinking MOA. If I was starting fresh I would go MIL, alas I am not starting fresh.

Having said that, the post above got me thinking about MOA methods for wind gap and elevation. Because, basically it is just about a method that you can quickly resolve a shooting solution. Quicker than an app ore returning to your compensated range finder as the target is changing distances.

MOA wind gap method. Looking at shooting solutions, you can do a method similar to the one Form outlines but with MOA. The method I will be trying this fall is to find a full cross wind speed value that gives you 1 MOA at 400 yards. MOA folks think clearly in terms of 4s and clicks (1/4MOA). So with a 100 yard zero that would put your 100 yard full wind correction at 1/4 MOA, 200 1/2 MOA, 300 3/4 MOA... and so on. My current primary hunting rifle is a 9mph full cross wind 1 MOA gun at 400 yards.

So my wind correction is one click per hundred yards with a 9mph base speed.

Elevation, the MIL method doesn't work great for my rifle and DA (11,000' elevations). So for now I am sticking with my range card attached to the side of my range finder. The table I use is very simple with one addition of the delta in clicks between and range and the next further 50 yard increment. That way when I dial, I know how many clicks to get it to the next 50 yards .

I am basically sending this post to 1. thank Form to getting the community thinking, and 2. see if anyone has used a similar wind gap method for MOA based systems.

Sounds similar to what is discussed here. Meat of it starts about 10 minutes in.


I haven't used it as I switched over to mils, so no personal experience with the method.

My 308 with 165s lines up very neatly out to 600. At 8 mph, the wind hold is 1/2 the yardage in hundreds. So at 400 yards, its a 2 moa hold. I can adjust off that pretty quickly in my head.

When I've tried to figure this out with higher bc, faster cartridges I haven't been able to get things to line up neatly but it's working for me for now with the 308 and a lower bc 6.5 round.
