243 Bullet Impact

[surjimmy]

Shooting 80gr ammo, you are only able to site your gun in at 25yds. How high of bulls eye should you site your rifle?

 

[sherrick13]

Wouldn't that also depend on the gun and the bullet velocity?

I normally bore site at 25 yards to get started then dial in at 100. I would not consider my 25 yard bore site as being zeroed at a longer range, until I could shoot and confirm it at the longer range.

 

[okierider]

That round is such a flat trajectory out to 200 that a 25 yard zero will probably need to be low. It is still rising at 100 and back to line of sight at 200, assuming scope height...............

This was in the back of my mind.

 

[Oklahomabassin]

Scope height?

 

[Okie4570]

.243 80gr soft point going 3300fps 100y zero broken down in 25y increments. 1.5" scope height

 

[okierider]

Scope height?

How far scope is above bore.

 

[Oklahomabassin]

How far scope is above bore.

Yep, that is what I asked him so I could answer his question?
