Are glass optics becoming obsolete?

I know they have other useful capabilities, and the 1100yd rangefinder would be great, but if the Zulu is zeroed at 50yds, the compensation won’t get you anywhere near 1100yds with airgun ballistics. Not even 300-600yds.

Soon I'll be putting 230 yards to the test with a texan.308 and at some point, i can find 400 yards if 300 works out. .308 Texan 150gr BARS slugs @ 990fps. 140 was easy.
