I was going to ask how do you measure distance, then I realized it might be easy, considering there's a scope
but now I want to ask... is the scope really reliable? does lighting play a role in estimating a target's distance?


Here's a post on my range-finder. The scope isn't often used to to measure distance, although it can be and I have done it many times. Technology rules the day these days.

The scope is primarily used for other things, seeing at distance and target acquisition.

So, is the the scope reliable. Yes. Of course, one needs to spend the right sort of money for reliability.

I use the Kahles 624i 6-24x50 with the SKMR3 reticle. Here's what that reticle looks like, an image from my ballistics solver.


It's important that the optics lets enough light in as it's a certainty that the shooter will shoot in low light and night time conditions. The turrets, elevation and windage must also track correctly. The post below explains that. It essential means that each click of 0.1 MRAD is indeed 0.1 MRAD all the way through the elevation and windage range.

Scopes also have to be robust enough to handle the field and various environments it will be used in. Generally you get what you pay for with a scope and going cheap is a bad way to go as it will render a solid rifle-system useless. The scope I mention here is almost $5,000 to purchase. A cheap scope would be about $500. Is my scope, as mentioned, that much better? Absolutely.

Anyway, this just a basic answer to what can be a very complicated question. I hope it helps.

You might consider it basic, but it covers everything I wanted to know about this in the modern day. Thanks! I wonder how snipers back in WW1 used to accurately measure distances, due to their scope' lack of tech.

They did it by eye and off charts based on typical things like a human, human head, car, etc. Fixed sized things. You say accurately. It wasn't really done accurately in the way we understand it today. Rangefinders can measure to the metre or less. Old-school snipers also didn't have scopes all the time, just iron sights. Not always, but often. It wasn't until World War One that scopes began to get used and developed.
