Finding YOUR Zero - shot by shot
- Thread starter cavedweller
- Start date
That depends entirely on how you choose to zero the rifle. There is technically an apex of the curve that will be the true zero, but if you “zero” your gun before or after that apex, there will be 2. One as it crosses the scope horizon and one as it again falls below the scope horizon. Again, the “mero” software will also show you both of these zero values. I “zeroed” my Impact m3 at 25 yards, but it also will be at zero around 45 yards with a slight holdUNDER in between. If I wanted to find the true “apex” of the trajectory that is possible.

Great place to ask this question. You ever have dope where the further out it drops and then comes back up and then drops again lol? Like a roller coaster?
Say
25y is 1.0
30y is 1.3
35 is 1.6
40 is 1.9
45 is 1.3
50 is 1.9
55 is 2.4
I know the answer but ive seen several people with dope like this.

cool... I have often wished i had my ranging course set up on a cable so i could run different targets in and out and try ranging on different textures and colors. But in the grand scheme of exercise my "fatness" and love for a good meal... requires i get as much movement as possible....

i have, but it was because the pellet was moving in a elliptical circle, which can happen. Bad Barrel.... ?? Or bad pellet?? but if you have the dope for it... go for it.

I guess you all really know the bullet never rises? It's just where the bullet intersects the line of sight. That stupid picture they put on ammo boxes and in articles sure confuses lots of folks.

Well, that’s honestly a matter of perspective. The bullet rises to your scopes line of sight.
The scope and barrel are not exactly parallel. I don’t think anyone really thinks the bullet is rising, but from the pov of the optic, it is.

Yes of course … it only falls to earth with gravity and intersects the scopes line of sight along the way
unless of course you have a micro guidance system in a .177 pellet

Yes spiraling is a better term, minimal at the barrel but can grow larger with increasing distance… ground thermal can also make a pellet rise… I’ve actually watched a pellet do this on the way to a KZ

Oh no, I have I'd guys argue with me about it. First thing they say, I can show you on an ammo box.

I've tried several commercially made slingshots over the years (decades actually) and found that I prefer an Over-The-Top (OTT) style that's homemade.
The "fit" of a slingshot is critical for consistency and the commercial one-size-fits-all don't suit my large hands so I custom make my own slingshots.
Here's a picture of a slingshot that I made for Tom Gaylord (BB Pelletier of the Pyramyd Air blog) and a link to a guest blog I wrote on how I make them.

I read that article several years back. I even downloaded a photo of your excellent work!
Very cool man!

Only as long as the barrel is at zero elevation.
For targets at ranges that require hold over (barrel elevation), the projectile will gain altitude linearly at first until aerodynamic forces and gravity bend the trajectory to an apex and the projectile begins losing altitude.

It's not gaining elevation from the exit angle of the barrel. Your wanting to be argumentative perhaps?

I apologize, my statement of fact was not detailed enough.
If the barrel is elevated 5 degrees above horizontal, the projectile's trajectory will be ( if there is little to no Lateral Throwoff or Aerodynamic Jump) 5 degrees above horizontal.
The projectile will gain altitude (RISE) at that +5° trajectory until aerodynamic forces (including gravitational pull) bend the projectile's trajectory towards its apex and the projectile begins its descent.
If the 5° elevation in barrel above horizontal is due to "hold over", your POA is below the initial trajectory of the projectile. As such the projectile, initially, is physically rising above your "hold over" line of sight before dropping to its intended " hold over" POI.

Thank you. You have supported my contention the Ammo companies have a misleading picture on their ammo boxes. Which support the thought many long time hunters and casual shooter be live, that in normal firing the bullet goes up before it comes down. You could be a great lawyer with your explanation, lol. I said the bullet is falling due to gravity upon exiting the barrel. I will stand by that. I did not bring line of sight into it. Your twisting words to argue . So we disagree.
