Rifle Scopes Scope use questions. Using mil dots and corrections.

[cirionrc]

Just a question on use of mil dots.

If I am shooting at 100 yards and using a second focal plane scope at 22x zoom (I know thats a lot but just hypothetical), and miss by 2 mils from the scope, do I adjust by 2 mils on turret OR would I need to estimate the distance of miss and divide that by 3.6"?

If I am shooting at 500 yards and using a second focal plane scope at 22x zoom (I know thats a lot but just hypothetical), and miss by 2 mils from the scope, do I adjust by 2 mils on turret OR would I need to estimate the distance of miss and divide that by 17.5"? (3.6"x5)

Thats the beauty of the mil/mil scope, if you are at the scopes 1:1 setting (most are at max). You correct by the amount you missed, anywhere. At 100, or 1000 a mil is a mil is a mil. Same applies for an moa/moa scope.

Now your scenario is a good example why it is important to consider FFP if you plan to range and correct using your reticle. x22 at 800 will be a decent field of view, but x22 at 150 yard will have a very tiny field of view, so if your target is moving(woodchuck or yote) it may easily get lost at that high of mag.

Now with enough triggertime and dope records you can hit targets at pretty much any range and mag with a SFP scope, just dial and shoot.

C:

With my limited knowledge, let me add only a few comments to what I believe was a very solid answer from roggom:

1). Matching reticle shown miss to turret adjust works if turret matches reticle! (Mil reticle, mil turet). Bushy, as just one example, has many scopes that mismatch. Stupid, but true.

2). Some SFP scopes have the reticles critical (zoom amount when the spacing shown on the reticle is correct) magnification set at other powers. An SIII 8-32 SFP is set for a 24x critical zoom, as an example.

3). Am sure u know, but the formula is miss distance / (yards/100) = correction inches to dial in on turret. So 8" miss at 400 yards is 8/(400/100) = 2" of correction. 8 clicks on most moa, 6 on most mil. (I cheat and consider a mil .33 instead of .36). All that depends on turret click spacing of course..

Warning! Take anything i say w/ a grain of salt. I'm quite a rookie.

firstly check on your scope manual that 22x is the correct setting on your sfp scope for milling as it will only work on one power setting.
then assuming you have it on the correct magnification setting you can forget all the maths.if you see you are off by a mil then either dial or hold a mil, distance does not matter.thats the beauty of mil/mil
