No. 1/4 MOA at 100 yards (typically one click on most scopes) is .261 inches because an MOA at 100 yards is actually 1.047 inches. So the difference would be less than an inch.

You are correct, I was aware it wasn't exactly an inch and couldn't remember the actual data. Thanks for clarifying...Yes.....kind of
Depends on if it is a 1/4 minute of angle or 1/4 of an inch. There are scopes that are both ways.
1 moa= 1.047" so 1/4 minute is .262
IPHY(inches per hundred yards) is 1 inch so 1/4 is .250
Why does it matter if it is MOA or IPHY, you just click the button on the ballistic calculator to be the correct one. It is only a problem if the turrets do not match the reticle.These threads always crack me up. MOA sucks...period. How many MOA scopes out there are actually true MOA and not IPHY or some crappy variation in between? Frank just tested an "MOA" Nightforce and guess what, it was actually IPHY. Explain that one.
Fractions are stupid, always have been, always will be. Base 10 math is easier, faster, and just better.

.1 is a fraction (1/10)
I was having to do mental math for my 1/8 MOA scope when it gave me .625 but if the app displayed it as 5/8 then it would be just as easy to dial to w.e whole number and count 5 past it the same way you would .5 mil (5/10).
If you are doing F Class or Benchrest then you will want to go with 1/8 MOA for the most granularity as well as almost all high power SFP scopes are in 1/8 so you wont typically get a choice.
If you are doing PRS style shooting then it only matters if you are communicating with another human being. If you are, then matching adjustments will remove the need to do a conversion.

Hell, just go with 1/20th MIL (.05 MIL) if you want to do the mental gymnastics for practice. Then you get the best of both worlds. You get to work in fractions and still say you are using MILS.![]()
Yea, it is advertised incorrectly but if the reticle is also IPHY then you just click a button and poof, problem solved.Because if your scope says it's MOA and it's actually IPHY, then that is wrong.
I also don't use fractions when communicating, I'd say "come up point 2" not 2 tenths.
Just to mess with you guys...
I have a Schuetzen-style Winchester Highwall M1885 (replica) with a Soule tang sight and windage-adjustable globe front-sight (adjust opposite direction). The sight adjustment is IPHY with 1/2" adjustment, no "clicks." You have to consider sight radius in your calculations (32" barrel plus sight offset).
You guys have it easy!
Is this still available?
Minute of Oh, Fuck!MOF? Minute of Frank?
Your ranging formula is wrong. It should be target size (inches) /apparent size (moa) x 95.5.One is not better than the other but, This is why I prefer IPHY -
1. ranging.
Refer to the above post by _Raining and see his link to ranging formulas. My retarded brain has a much easier time ranging targets with the formula:
Distance to the target in yards = size of target in inches/Image size * 100. I can do this math quickly in my head without a calculator. No need to convert target size to yards, no need to multiply something by 27.77 or 25.4 which I cannot do in my head. Multiplying any number * 100 just means you move the decimal 2 places to the right. Try a few examples and you will see how quickly it works.
30 inch target measures 3 moa = 1000yards.
30 inch target measures 5 moa = 600yards.
24 inch target measures 3 moa = 800yards.
Super simple for me, even when rough fractions result for 25, 50, 75 yard increments.
2. wind holds
My formula for wind holds with my 243 is:
wind hold in moa = distance to the target in 100s of yards * wind in MPH/20. Again a formula I can do quickly in my retarded brain without a calculator. I find it simple and fast. Yes, I understand that there is a 4.7% difference between MOA and IPHY but who cares. Wind is continuously variable anyway so I dont sweat the difference in wind calls. I find the above formula works for most magnums as well as the currently popular 6.5, and 6.0 cartridges, and most other "flat-shooting cartridges".
For old school cartridges like 308, 3006, etc., I just use 10 instead of 20 for the denominator in the above equation, which is even easier to do in my head than dividing by20. For the 223 I use a denominator of 8, which is pretty easy as well.
Examples
300 yards with 20mph full value wind = 3*20/20=3moa hold. for a half value wind, 1.5moa.
500 yards, 10mph full value wind = 5*10/20=2.5moa hold. for half value wind, 1.25moa.
I like IPHY for the speed of calculations I can do in my head, especially for wind because its continuously variable and I can recalc quickly with a change. I was originally taught windage/elevation adjustments in MOA with the constant reminder that there is that 4.7% error due to the 0.047 inch difference at 100 yards. Therefore going to IPHY was natural for me because it corrects for that difference.
Obviously experienced mil guys can do their calcs just as quickly but for me, IPHY gets me on target super quick. It works best for me so I use it.
Disclaimer: I am not nor was I ever a sniper or even in the military.
So your reticle is IPHY? I guess I didn't understand that part.Skookum, again that is why I like IPHY. it corrects that 5% error and simplifies the math to multiply by 100 instead of 95.5.
Is USO still tier 1?Is there even a "tier 1" optic that is IPHY/IPHY these days outside of USO?
Is USO still tier 1?
What color, as they differ in size?I'm holding out for MOCH....
