The Sightron web site states that their SIII 6-24x50mm LR Mil-Dot cross hair is 0.7 inches thick with the scope set on 6X power, but only 0.1 inches thick with the scope set on 24X power. These dimensions are at 100 yds. So with the scope set on 24X, the thinnest cross-section of the crosshairs should cover 1" at 1000 yards.
I didn't specifically test or verify this on my scope in the field - I guess mostly because the size of the crosshair looked fine to me with the scope turned to the 24X setting. Next time I shoot I'll specifically examine the crosshair width on target and see if those dimensions are correct.
BTW, I never said I thought the crosshairs were too thick for hunting. I believe Nathan, the gentleman I purchased my scope from, said he thought the crosshair was too thick for his competition shooting. He also stated he'd never looked through a scope that had better glass than this SIII.
In my opinion, the width of the crosshair in my SIII 6-24x50mm LR Mil-Dot reticle is just fine - a non-issue.
If you buy an SIII, my primary words of caution are - make sure you buy and receive the current model SIII. It sounds as if there was an earlier Generation SIII that may not have been up to snuff.
I suspect Ernie has the earlier Generation SIII or else a Sightron "second" (Leupold). And I'd guess jsthntn247
is in the same situation...
If they ever look through the current model SIII, their SIIIs will be FOR SALE!
I'm throwing out the tinder here but nobody's biting... Not even a nibble!
