Rifle Scopes Sightron confusion

[EventHorizon]

I'm looking to get a 8-32X56 Sightron for F-TR and general practice at groups and dot drills. I'd prefer to get a Mil-Dot reticle but am wary of thickness. I'm totally confused by the dimensions of the reticles of the Mil-Dot reticles between the scopes with MIL adjustments and those with MOA. The CM adjustment (.1MIL actually) measure the reticle thickness at .2 inches at maximum magnification (that seems very thick at 32x for a SFP scope). But the scope with the Mil-Dot reticle with MOA adjustments measure at .07

What gives? Why can't the MD/CM have the same level of fine reticle as the MOA adjustment scope?

Here are the reticle specs:

Sightron <span style="font-weight: bold">8-32X56LRMD/<span style="color: #FF0000">CM </span></span>

Min Power
A 108
B 10.8
C 3.6
D 2.4
<span style="color: #FF0000">E.6</span>

Max Power
A 36
B 3.6
C 1.2
D .79
<span style="color: #FF0000">E.2</span>

Compared to:

Sightron<span style="font-weight: bold"> 8-32X56LRMD/<span style="color: #FF0000">MOA</span></span> (1/4MOA)

Min Power
A 106.3
B 10.63
C 3.38
D 2.25
<span style="color: #FF0000">E .28</span>

MAx Power
A 26.6
B 2.66
C .84
D .56
<span style="color: #FF0000">E .07</span>

My Man,

The reticle is the same for both. And both index the mils correctly at 24x, not 32x.

Not sure where you found the specs for the second reticle but it is incorrect

Re: Sightron confusion


Looking at the Sightron online page, those are not the numbers they have listed for SIII SS 8-32X56 LRMOA.

Sightron


And apparently Sightron has more than 1 MOA type reticle....

Some are indexed @ 24x, like the one you have listed above and some @ 32x apparently.

Hey Scott, thanks for chiming in.

Here's the page to the first scope

Here's the link to the second

I was comparing the two scope that are both Mildot reticles but one is in CM adjustments and the other in MOA. The links above take you directly to the ones I'm comparing.

Re: Sightron confusion

There is an error on the website. The dealer's catalog has both the MOA turret and CM-turret mildot 8-32x56 as the exact same dimension synchronizing on 24x.

Hope this clears this up

Re: Sightron confusion

Thanks Scott.

So what is the correct value?

What you published for Mrad/CM

Re: Sightron confusion

I think Sightron got their terms mixed up. .2 is the reticle thickness at 24x as .2 is exactly one third of the thickness at minimum power 8x. They're giving reticle dimensions when the magnification is at the correct index level, not at the maximum magnification.

So @ 8x reticle = .6

Increase mag by 3 to 24x ( correct index value to range with reticule)= .2

I'm guessing at max magnification of 32x the reticle is .15. I'll call Sightron on Monday to see.

Re: Sightron confusion

Spoke with Sightron - the reticle numbers are in fact incorrect and a fair bit thinner at maximum magnification for the Mil-Dot reticles (this is great news!).

I'll be getting an email from them soon with the correct numbers and will post them up here.
