If using yards, 3.6 x yds(in 2 whole numbers then decimals) x mils measured

So, 1050yds and you measure .2mil group

3.6 x 10.5 x .2 = 7.56”

1500 yds and .3mil group

3.6 x 15.0 x .3 = 16.2” group

There are many other formulas as well.

It’s not precise as they don’t perfectly line up.

And .3mil is a bit larger than 1moa

I could see that. I was just giving you shit because it’s easy for us moa guys. It’s just one of those things that I find funny about the gun world. Why not just measure it in Mils and leave it at that?Its mil scope/reticle

1mil at 1000m is 1m

1mil at 100m is .1m or 10cm

. 1mill at 100m is 1cm or .01m

For rangeing you need a known value to measure.

For measuring you need a know distance.

PoiAre you trying to measure a group or poa vs poi? What's the range? What's the scope?

He doesn’t need quick match in this situation and asked for standard measurements.

1mil at 1000m is 1m

1mil at 100m is .1m or 10cm

. 1mill at 100m is 1cm or .01m

For rangeing you need a known value to measure.

For measuring you need a know distance.

You need 2 values to solve for the third.

Distance to target (meters)

Measurement at target (cm)

Mils (on scope)

Cm÷mil×10=m

Mil÷10×m=cm

Cm÷m×10=mil

Edit for correction

Distance to target (meters)

Measurement at target (cm)

Mils (on scope)

Cm÷mil×10=m

Mil÷10×m=cm

Agreed but I think the op said he can't get out to the target, so assuming this is true, he would need a range finder to validate the distance, and an object at the same distance of known size that he can measure with the reticle. With these two he can as you indicated measure the size and spread of the impacts.You need 2 values to solve for the third.

He's kinda stuck if he only has one.Agreed but I think the op said he can't get out to the target, so assuming this is true, he would need a range finder to validate the distance, and an object at the same distance of known size that he can measure with the reticle.

What part of San Jo you from? I'm over by Campbell.

Right where 87 and 85 meet, I run up to los altos for short range stuffHe's kinda stuck if he only has one.

Huh?I was trying to do this today. You need to find out the hash mark values of your scope reticle.

No, were away for the weekend, I will probably shoot up there next Saturday morning, let me know if you plan to.I'm up there at least once a month. in fact I'm in the cave now working on some loads I'll be up there testing next week. You shooting Avenal tomorrow? I was hoping to but Easter and family so next time.

Yes, you do.I was trying to do this today. You need to find out the hash mark values of your scope reticle.

I'm going to guess that looking at the picture through his scope that the little grass in the rocks at 2 O'clock is about 24" or 60cm, and on his reticle looks to be about 1 mil.

If he looked around nearby he could measure a similar grass and get a better idea.

So

60÷1×10=600m

If the grass is more like 18" or 45cm

45÷1×10=450m

So using reticle to measure splash (poi) vs point of aim should give you mils to adjust?Yes, you do.

This is the danger your eyes can get you in trouble with as we discussed in the other thread the other day estimating size with your eye. For example how sure are you the grass is 24" and not 18"? Sure you can look around for like grass and fortunately for you mother nature likes patterns and has evolved human eyes to look for patterns and you measure some grass near you and it validates your 24" thought that all grass that looks like this is 24". Our eyes do this to us all the time especially in the two dimensional space of looking through glass. Problem is the grass really is 18" and now your range is off by a factor of 25% and we have committed a nice type 1 error. Really really hard to accuratly measure 6" at distance but can be done...alot of sniper school classes loose guys on range estimation.Yes, you do.

Good skill to have really hard skill to master proficiently. I like your style though, master it you are on the right track with your known size objects. I used to carry a tape measure with me on every patrol and I would occasionally measure objects in the villages just in case batteries died .

Lol, yeah. I just dropped the measurement pin in front of the line as an example.Is this los Altos, my lrf show 103y there?
