That's why I don't visit or post here often.

Sorry, I've not had problems with any Swarovski scopes in low light, and I've done side-by-side of testing in low light. If there is a transmission problem with the scope optics, you would have noticed it in daylight. I can only suggest you keep the magnification below 7X so that the exit pupil...

This isn't the first time I've clicked on a highlighted post from the email and found it was already removed.

Agreed - in principle. However, sorting out the source of the problem is usually much more effort than simply lapping the rings. Even a minor misalignment will usually result in ring marks on the scope tube. If at the start of the lapping process I can see that the rings are way out of...

I always lap the rings, use RingTrue tape and use blue loctite on the screws. https://www.highpoweroptics.com/ringtrue%C3%82%E2%84%A2-tape-three-scopes-p-24944.html Using this process, I never have problems with scopes slipping on magnum or 50BMG rifles. I don't have ring marks on any of my...

I used to do it this way - but it takes three tools (EXD tool, level, and plumb line). Now I use the RingTrue Alignment Tool. It's cheaper ($40) than the EXD tool and does the work of the three tools shown in 436's photo. https://www.highpoweroptics.com/ringtrue™-reticle-alignment-tool-p-30656.html

I agree that cant error is worse, and that your scenario was exaggerated. I've tried to eye-ball reticle alignment many times. I can't see the bore through the receiver because I'm looking at the reticle. I'm looking at the rear end of the receiver and guessing that the bore is centered in...

Maybe, but Len doesn't have to honor the warranty. I often hear Vortex customers post about how Vortex replaced a bad scope and their customer service was so good...

You are correct IF the shooter maintains the 0.44" POI offset when the rifle is "zeroed" at 100 yds. But someone would do that only if they knew that a .44" error existed at the muzzle. Usually they don't know that and proceed to zero the rifle with zero POI offset. Then they convert the .44"...

Your Scenario 1 analysis is not quite complete. Most folks will zero at 100-200 yds. For a 100 yd zero the .44” horizontal POI offset in your calculation creates a .44 IPHY angular POI error that is proportional to target range from 100 yds. At 1000 yds, for example, that angular error...
