MOA vs inch scope click intervals

Any real advantage either way?

I know they're only very slightly different but as long as you understand how much adjustment you're actually doing is it just personal preference?

Do you mean MOA vs Mil? I've never seen a scope that has adjustments in inches. Most scopes have 1/4 MOA adjustments (1 click equals 1/4 inch at 100 yards, 1/2 inch at 200 yards and so on) if your scope had quarter inch click values in theory it would be the same thing but only if you knew at what range that adjustment shifted your point of impact 1/4 inch.

If you did mean MOA vs Mil, the most important thing is to match the adjustments to the reticle. If you're using a Mil dot scope then having the adjustments in parts of a Mil makes it easier to calculate your windage/ elevation changes when you use the Mils for range estimation. If my memory serves me right 1 Mil is just over 3.5 inches at 100 yards and adjustment values are usually .1 mil

I mean some scopes have "1/4 MOA" adjustments and some have "1/4 inch" adjustments.

I know the two measurements names are largely interchanged, if someone shoots a 1" group they'll say they shot 1 MOA or vice versa, but as you know they're not exactly the same.

1 MOA is 1.047 inches. Close enough to call them the same thing in most cases.

Maybe to rephrase my question, when would someone NEED adjustments 1/4 MOA adjustments and 1/4" adjustments would not be suitable?

Hope that makes more sense.......

Hmm I've never seen one marked as 1/4" adjustments (not saying they don't exist) as stated above it would only adjust POI 1/4" at a given range. Perhaps it's just implied that it's that much adjustment at 100 yards which would make it 1/4 MOA adjustments anyway

The Weaver 40/44 series scopes adjustments are quoted as 1 click being "1/4 inch at 100 yards". Not MOA.

Don't know of any others but there's one.

Yes, 1 MOA is 1.047 inches at 100 yards.

1 MOA is 2.094 inches at 200 yards, 3.141 inches at 300 yards and so on, as you say shooters will round the number to 1:1 as that's close enough for 99% of peoples purposes.

In the end they're both just units of measurement and neither of them do any of the shooting or measurement for you. You still need to do that yourself so as long as you know what measurements and ranges you're shooting with you'll get the same result.

MOA is good to have a universal measurement you can apply to different things and incorporate into ranging targets with an MOA reticle.

If you're just punching paper out to a few hundreds metres at the range where the distances are known it's neither here nor there.

For strictly target shooting many Mil scopes let the shooter down with .1mil adjustment turrets. Each click is 10mm at 100m which would be 50mm at 500m

While 1/4moa clicks is common in hunting sms opes many target scopes use 1/8moa clicks making each click around 3.3mm at 100 and 16mm at 500.

You're missing the most important thing.

Saying MOA makes you sound cool and tactical! No understanding required! :lol:
