MPH gun

Yes. Figure out at what MPH a 3 o’clock wind equals 1/100 of your range in mils.
So if a 5mph wind shows you .5 mils for a 500yard target, you have a 5mph gun.
My gun seems to be very very close out to about 900m or transonic With 6mph. After that in need to add about .1 mil.

Everyday Sniper Section has tons of Posts on it
Here is something I put together to help people understand this better:
You have already seen @lowlight suggestion to look at the Everyday Sniper Podcasts, but here is a similar thread from last summer. Same material and authors, so worth reading:
Calculating mph rifle
At a recent match, many on my squad were describing their wind calls in terms of mph, by saying eg: I used a 5mph wind( rather than describing it in terms of mils). These were good shooters doing this. (I just got on their squad by accident). Where can I learn about this technique, and...

I’ve gotten to where I don’t even look at the g1 BC.
True data at distance. Then plug in 4,5,6,7 mph full value wind. Look at the chart and pick the one I want to use.
Basically:
223/308 = 4/5 mph
6mm/6.5 = 6mph (slow rounds might be 5)
Fast 6’s or very high BC = 7 mph

Cool, so plug in a full value wind, and see at what MPH wind equates to 1/100 of your distance for your wind hold. If you’re shooting 308, it’s likely gonna be 4. MAYBE 5 if you’re really pushing your velocity.
Shot out to 984 yards (900 meters) on Saturday, wind at about 11 mph almost full value. I’d setup Strelok Pro using Jacks information, gave me about a 5mpg gun. It worked, I’m not good at judging the wind and this was my first time past 600 yards with my Tic Tac, it worked well.
shooting at a 2ft sq target on a 4ft board. 17 hits on the target and the other 3 still hit the board. Sadly no photos.
Thanks to everyone who has contributed on here (not forgetting lowlight).

This is the StrelokPro table I used to determine the 5mph.

We had winds this weekend go from 6 MPH on Friday to 12 MPH to 25MPH on Saturday
The MPH gun system works, it's what we use, and everyone was getting great hits with the data provided

Yes. Just use meters Instead. I would use 500 meters to match 0.5 mil rather than 600 =0.6 to find your gun mph. It absolutely works in meter too
Awesome,I should of said I’m still using moa all I have on my hunting rifles. But if it’s the same for mils moa should work too. Thank you Jack the work that you’ve done for this, wind rose and gravity Ballistics is awesome.
