Your zero is an ever-changing thing, and is subject to temperature change, elevation, humidity,and other atmospheric conditions (let alone the general physical bumps and drops along theway). You can use these as a quick reference or compliment to your ballistic charts for a goodstart. Remember to go out on the range and test it for yourself. As the proverb goes “Доверяй,но проверяй” (Imagine Ronald Reagan saying, “Trust, but verify”)

These aren’t the only visualizations we’ve come across, but the standard IPSC target may bemore relevant to your needs than say, a scaled Cookie Monster in a desert. As always, yourmileage may vary.

There’s also a ‘He-Man on Mars’ version of this

Joshua Ford you should wear a bump helmet of some sort so you don't bruise your forehead when youlean in to lick the window. That's not our article, we're sharing something we found. Of course you prob'lyknew that, since you'd undoubtedly have read it before posting something ill-advised and borderlinemoronic, right? Nah. You're probably just joshing around with us or trolling, otherwise you'd be seen as anincompoop, so ha ha! Well played! You got us! Enjoy that GREAT READ! DR
