Default Maybe a stupid question about zeroing in a rifle

F I were to zero it in at a 100 yard range and saw a deer at 200 yards would I need to adjust for the increased distance? Or is it basically set for all ranges? I'm sure I would have to compensate some and shoot a little higher than what I'm aiming at to compensate for the drop, but I should be good all around, no?

Depends on the caliber to a degree, but for the most part, yes you compensate by aiming a bit higher.
If you know the ballistics you can calculate it out.

Look at the ballistics for your caliber.

I like to Zero at 200. Then you are a couple inches high at 100. But if you zero at 100 you are more than a couple inches low at 200. Zeroed at 100 can be close to a foot low at 300 depending on the caliber. I find 200 a good compromise.

+1

Roughly 2 high at 100, 8 low at 300, 18-24 at 400 for most centerfire rounds, depending on caliber . Op, are you shooting centerfire, muzzleloader, shotgun slugs?

To the OP- when a bullet is fired, and the bore is tilted above the horizonatal, the bullet starts up, and crosses the line of sight. If you are zeroed dead on at 100 yds, then at 100, as it is coming down, it crosses line of sight again. Beyond 100, it continues to drop. You need to adjust the point of aim at greater distances.

Give me the cartridge you are using, I can give you the data of where bullet will be at different ranges.

Agree on the 200 yd zero for MOST high powered rifle loads.

Thanks for all the helpful tips guys. I'm using a .30-06 savage axis.

The best range I have by me is 100 yards, the first time I fired it was something like 50 feet at a crap range. The rifle was high and to the right at that range straight out of the box.

Will try to find a better range to zero at 200.

If all you have is a 100 yard range, just set your scope up to hit 2 inches high at 100. That is a good baseline to work with. Make sure you are dead center left to right. 1 inch to the left is 2 at 200 and 3 at 300 and so on.
