I originally started a thread HERE trying to determine which 3-9 scope I wanted on my AR-15 for a coyote/predator setup. I'm not sure why I didn't include a Sightron, since I have a SII 4-16x42 w/ 1/8 target turrets on my Pac-Nor barreled 22-250.
The Vortex has more MOA adjustment than the Sightron. The Vortex has a slight edge in FOV. The Sightron is almost an ounce lighter. The Vortex is argon filled and the Sightron is nitrogen purged. I'm guessing argon is better.
Vortex seems to have done a good job in helping the hunter determine bullet drop IF you want to sight in your 223 at 100 yards. Their chart isn't perfect though. Compare their chart with ballistics calculated with Point Blank v1.8a which I picked up from the Hunting Nut website.
I prefer a 200 yard sight in so their chart does me little use. I would still need to figure it out on my own. I would need to call Vortex and find out what the reticle MOA measurements are at different magnifications, as their reticle chart is for the highest magnification.
Sightron gives you a Ballistics For Reticle Drop PDF, but it doesn't say at what magnification you're supposed to be at. At least Sightron gives you the reticle MOA measurements at Min and Max magnifications.
So, which of the two scopes has better optics?
Yeah, I know I can get the Sightron for about $225 after $75 rebate, but I'm trying to keep price out of it.
