Zeroing
- Thread starter AnimalHitman

If you shoot at certain inclines gravity effects the projectile as a example if your shooting up at a bird in a tree at 50yrds your poa should be lower than a target level to you because gravity will cause your pellet to drop faster shooting level than shooting up.

Scope "cant" (lean), can introduce errors in your point of impact, especially as distances get longer. First I level the airgun. Then I level my scope at the turrets, then site through it against a string which has a weight suspended on it (to confirm the reticle is not out of line with the turrets). Errors are frequently additive where I live, it is rare for me when they cancel each other out... luck of the draw.

I'm not talking about cant. I have my scope and rifle leveled with regard to cant. I have a level on the scope, and the Pulsar has an integral level. The are both synchronized with the vertical hair of the reticle (I did the weighted string thang.) I'm talking about the barrel being leveled on the y-axis (zero vertical angle) - Pitch, not roll.

Sonny, thanks for that 
. I'm going to level the barrel (zero vertical angle) when zeroing just to be safe.

I just put the numbers in Chairgun, with the barrel level I have a 2 mil holdover at 69yds. With the barrel at a 35 degree angle up or down I have a 1 mil holdover.

You were right; it actually arrived early on Saturday! How did you know? You must do business with Cabela's.

The fact that shots taken up hill or down hill hit high especially at relative short distances has almost nothing to do with gravity. It's more a related to geometry and the line of sight. Complicated subject GOOGLE it

bubbler, that's an extremely good point! This is why I use a tilt-technology laser rangefinder. It gives true horizontal distance regardless of angle. By having the true horizontal distance. I am able to use Chairgun's zero angle input per se.

The reason the projectile hits higher when shooting at an angle is all about gravity. Compensating by using the correct hold-under (or dial under) for this gravity effect is all about geometry.

outdoor, I couldn't have put it better myself! That evinces a solid understanding of the dynamic.
