Can someone tell me if I understand mil dots correctly?
The target is a 72 inch tall man. He spans 5 mils at the current range:
Distance = 72in * 1000/5mil = 14400in = 400yd
I then apply a holdover, assuming I have 36in of bullet drop at 400 yd with the rifle zeroed at 100yd. Assume at 400yd,1 mil = 14.4in
To compensate for 36in of drop:
36in/(14.4in/mil) = 2.5 mil holdover
>no mention of magnification
Yeah... nah... start over. Watch a Youtube video.

I was under the impression that under a specific magnification listed by the manufacturer of the scope the distance from one mil dot to the next is standardized.

FTFY

Forgot to mention that I was told this is for SFP scopes, whereas FFP scopes can be used at any magnification for range finding on account of the proportionally scaling reticle.

We use a different system, based on 6300'. The end result is slightly more precise, but not that much.
72 inches=~180cm
1,8m/5'=0,36km=360m

magnification does not matter at all. Mils is a measurement of angle, not distance.

That's what I was thinking as well, considering all the manuals I've read assume you have your scope set to the proper magnification for accurate mil readings and do not mention magnification at all.

though the holdover differs depending on what rifle and caliber your shooting, you need to find those specs on your own.
Realistically, you're generally going to have your rifle zeroed at 300 and use 1 mil holdover for every 100m. That's how i was taught though.

I thought the rifle, caliber and zero distance only affected holdovers insofar as dictating the bullet drop.
>>34462339
Well, if you have a variable power magnification that doesnt change the reticle with the magnification, i suppose it would matter.
>>34462397
Yes, the barrel length, caliber and your zero distance will affect the holdover. I learned one specific platform, but i have no idea what you have. I would imagine that it wouldnt differ too much, but i still want to add a "your mileage may vary".

Oh, i misunderstood what you meant. I mainly used a 10x scope (.308) with the ability to adjust for windage and elevation. Under most circumstances, we would have our scopes set to zero at 300m and for fast shots i would simply use holdover rather than adjust those settings.
