Rangefinding using Mildots

lefthooker

Howdy

Been reading up on using a mildot reticle to estimate range. I can understand the principle & the calculation involved but there's no mention of the optimum mag. to set your scope to. I'm using a Bushnell 5-15x40 & was wondering if anybody could tell me what mag. to set to to use this facility.

Thanx.

For scopes of 22 power (top mag) or less it is usually the highest setting. For scopes with 23+ power it usually is around the 22 power.

So for your Bushnell it would be 15 power.

Thanx for the quick reply Ez

See if one of the numbers on the zoom ring is red or different colour and that will be the setting where the mildots are correct.
On my Bushnell 6-24x50 it's the 12 digit zoom that's correct.

Good read here

What about a zeiss 4.5x14x44 mil dot

Rule of thumb is if the scope is 22 power or less then use the highest mag setting on your scope. If your scope goes up to 32, 42, 50 , 60 power then look for the ranging mark on the scope. This is usually marked with a dot, red mark, red number, letter "R", etc.

So unless the Zeiss website says different using your scope at 14 power will give your "hash" mark/mil-dots on the crosshairs the true MOA/adjustment.


As i said this is "rule of thumb". It does not always hold true for every make/model of scope. However if you are having trouble finding definitive information about your scope start witht he highest and work back.

Does that make sense?

sorry dax but rool of thumb will be no no good in this situation. it has to be bang on or its no good.

my IOR is set for 10 power and its 4-14x50
my hawke is also 10 power and its 6-24x56.
other scopes are different ie some are 12 and so on
all scopes are different and unless you know from the manufacturer lit then you are only guessing.
the best way to check is to mark a target evenly at 3.6" spacing then set it up 100y away and adjust your scope until the milldots are aliened with the marks on the target then you will have your correct magnification for calculating distance.

My scopes it's 11 on the 5-5-22 and 22 on the 8-32x56.

As the lads said, it's normally marked on the scope.
I have a dot on one scope and an R on the other.

Must scope sites have it stated on there website

roosman

I have a Bushnell 5-15 and its 15x for using the mildots.

One shot on kill

very interestin read.

BUT

What i have i done to you? :eek:

I merely tried to help the OP. I do not know about every scope. I know about a few. Do you know about all scopes and their range settings?

If you check back through my posts you will see i DID guess and made it abundantly clear that my comments were "best guess" and that for proper information a person should check the website of the scope manufacturer.

You might want to ring Nightforce as even their own website says that the ranging setting for 5.5-22 scopes is 22 power. Plus its not what you said before.


I gave an opinion, and with the replies from other users we see that it holds true for some and not for others, hence the reason the OP should read all the posts and see which matches his scope.

it also depends on whether the scope is first or second focal plane!!

Well to add my 2 cents I use the missing mildot in the centre of the reticle, where the cross hairs cross. :rolleyes:
Lazer range find first and then adjust the range with the tactical turret. Use a drop chart and you won't need to do the math.

Bushnell 10x40 3200 Elite tactical that sits on my CZ varmint 22lr. I've taken many a Kudo with it on African safari's .

I should have said 11, type error!

Clive you never miss an opportunity to post a pic of your cz varmint, I'm starting to wonder if it was a hard birth???
Anyway there's no markings on the zoom ring of my Legend, I'll bang it up to 15 & see how I get on
