hi all! was wondering if anyone could advise me on 1/8 moa turrets. So say at 200 yds, would one click equal a qaurter making 4 clicks 1 inch thus making a rotaion of say 0 to 1 on my turret 2 inches at 200 yds since there are 8 clicks to 1 minute at 100? Any further explanation would be greatly appreciated..

Re: 1/8 moa turrets
The best way I found to remember is take the first number in the yardage and substitute for the top number of the fraction in the scope adjustment. For example, 1/8" click at 100 yards is 5/8" click at 500 and 1/16" at 50 yards, 1/4" click at 100 is 6/4" or 1 1/2" click at 6 hundred yards and 1/8" at 50 yards. Seems to work for me. Others may chime in to their methods.

Re: 1/8 moa turrets
Its probably better to try to start thinking in angular terms of MOA instead of inches. The conversions can get tricky on non surveyed ranges and it just get confusing.
This confusion contributes to the wide adoption of MIL or MOA reticles. Shoot, measure, correct, repeat.
If you need to figure out how many MOA off you are at a given range, and have to measure in inches, the formula is below.
MOA = 95.51*Measurement in Inches / Distance to Target in Yards

Re: 1/8 moa turrets
A "minute of angle" is in fact a measurement of angle, not of length. 360 degrees in a circle. 60 minutes of angle in a degree.
One minute of angle is:
1.047" at 100 yards.
2.094" at 200 yards.
3.141" at 300 yards.
4.188" at 400 yards.
5.235" at 500 yards.
etc.
For 1/8 MOA clicks, divide the inch amount above by 8 for the distance your point of impact will move per 1/8 MOA click at the given yardage.

Re: 1/8 moa turrets
okay...I have some understanding of minute of angle and that it is based on a circle broken into degrees of minutes and seconds, 1 moa or 1/21,600 of a circle and that it just so happens that 1 moa equals ROUGHLY 1" @ 100 or 2" @ 200 etc, I'm just trying to figure the actual value of one "click" with 1/8 in moa turrets. My other scope has a "click" value of 1/4 at 100 yds, so at 500 one "click" has a value of (again roughly) 1 1/4 right? So here's the bomb..is that value the same on 1/8 in target turrets? If one "click" is 1/8 at 100 with 8 "clicks" equaling one minute...does that mean at 500 one "click" has a value of 1 1/4 making those 8 "clicks" actually 2 minutes or roughly 10 inches at 500?? I need help!!??

Re: 1/8 moa turrets
1 MOA @ 500= 5inches (roughly)
Your scope click = 1/8 MOA
5/8= .625 inch per click @ 500 yards
Thanks for the reminder why I spent the $ for FFP MIL/MIL

Re: 1/8 moa turrets
kay got it....so ex. 600 yds...one "click" =.75 making 8 clicks = 6 in. or 1 moa (approx) @ 600yds, 4 "clicks" = 3 in. or a half minute @ 600 and 2 "clicks" = 1.5 in. or quarter minute @ 600..sound right?...thanx guyz for all the help...the scope in question incorporates a lrx reticle with predetermined measurements for range estimation and holdovers for elevation and wind at 10X but I thought it would be good know my kit in and out...again thanx guyz....ps..someone correct me please if I'm wrong with those numbers......

Re: 1/8 moa turrets
I hate to burst your bubble, your over thinking this whole process, stop thinking in the unit of measurement you know and learn angular measurements, and what ever system you go with, DO NOT COUNT CLICKS, I just switched from all MOA to a all Mrad scope, I wish I never bought that MOA scope, it's going back to Nightforce for a conversion when funds exist.

Re: 1/8 moa turrets
The most important point that some were trying to make is that 1/8 MOA is always 1/8 MOA......no matter the distance.
One click of your adjustments is 1/8 MOA at 100, 200, 300, 150, 231......it does not matter the yardage.
From here, if you want to convert from angular units of measure (MOA) to linear units of measure (Inches) you must do some math.
Scope adjustments are not "linear" adjustments. Read that sentence again and again until it sinks in.
If your adjustments are truly 1/8 MOA, then each click represents a "linear" adjustment of about .131" per hundred yards, .262" for 200 yards, and so on.
For odd distances, use the figure of .131" times the distance(yards) divided by 100 to get the linear click value for the distance.
Example: One click at 435 yards would move the impact point by .57". (.131 X 435 / 100 =.57)

The problem is a lack of understanding for angular vs linear measurements and how they corelate.
That problem cannot be overlooked with a different angular measurement system.

Re: 1/8 moa turrets
outstanding explanation RAF now if you can explain to me how ya came up with the ".131" I'll go to bed feeling pretty smart (and grateful)

Re: 1/8 moa turrets
MOA equals about 1.047" at 100 yards.
A 1/8 MOA click would be 1/8 of 1.047.
1.047 divided by 8 is .130875.
I rounded it to .131.
Corrected.

Re: 1/8 moa turrets
Rafael....just for clarification you should have rounded it to .131 and not 1.31
1/8 MOA is way to fine of an adjustment for tactical shooting. I would stick to .1 mils and run with it due to standardization with adjustments and reticle as opposed to MOA side of things.

Re: 1/8 moa turrets
The MOA Guys confuse themselves with this crap but will argue how great it is...
Look at all the math here and still, it won't help the guy understand his adjustments any better.

Got a decimal out of place. Thanks, but you knew what I was saying.
I agree 1/8 sucks for this. I have a Nikon with 1/8, but have not used it for some time.

I did not call MOA superior, and do not believe it is.
I retain the position that none of them are superior to the next.
I screwed up, this time with my typing......it won't be the last time.

Re: 1/8 moa turrets
I, however, owner of a 12x42x56 Bench Rest Scope which comes with 1/8th MOA turrets now have a fairly easy formula to figure out how to put that bullet in the middle of the zero on the number 10. (lol)

Re: 1/8 moa turrets
Stop thinking in clicks!
If you need 4 3/8 MOA, turn the dail to 4, then 3 clicks. This is a hell of a lot easier than counting 35 clicks.
Try not to get to caught up in "what equals how many at what distance". It is important to know, but not needed in the real world.
Just dail what your dope tells you and be happy.

Re: 1/8 moa turrets
Thanx for all the info...Raf pretty much hit bullseye with his explanation...and I agree it makes more sense to adjust using the dial's whole numbers than "clicks" that why I tried to use that term loosely..anyhow thanx much duders and I will be using this info very soon
