Rifle experts- Help sighting in rifle - Ballistics question

[Leef]

Any of you guys have a minute to give me some help? I have some questions about sighting in a rifle and the ballistics chart on the ammunition box. Headed to the range in about an hour and need to figure something out. Please PM me your phone number if you have a minute this morning. Thanks

Forget what that box says. Test it

I agree, yet have some questions just trying to understand what the trajectory (inches) means.

The trajectory is probably below or above line of site I think. I don't remember what one of those chart looks like and I've never really paid much attention to them cuz I just shoot.

-1.5 usually means below line of site
0 means on line of site
+1.5 mean above line of site.

I think that's how it went. Post a picture of the box.

In a controlled setting, the ammunition manufacturer will test the flight path of the bullet. This is done with a specific rifle, that has a certain barrel length and twist rate. Based on the muzzle velocity out of the said rifle, the bullet is expected to hit at “X” inches above and or below the point of aim at different yardages. This is usually shown at either 100/200/300 yards. Example: If you have your rifle and scope dialed in at (200) yards, when you aim dead center of the target at (100) yards it will be “X” inches high. If you then take the next shot at (500) yards it will be “X” inches low. Only problem with this is that you’re not shooting the rifle that was tested so your velocities and point of impact will not be the same. Even if you told us that you found out exactly what rifle the manufacturer was shooting it will still not be the same due to the manufacturer of the rifles tolerances. This is why the ones who posted above stated to just shot it and test it to see what you get. Hope this helps. Y’all take care.

Not to mention that the off the shelf ammo may have up to 75-100fps difference out of the muzzle.

What chambering and ammunition are you shooting?

make it easy on your self...sight in a about 40 yards about 1/2" high.
Then move out to the distance your looking to site in for.

It's a "ballpark figure" probably shot with a 26" barrel.
