Thread: Sighting 200 yards at 100 yards

As such, I dialed the scope 2cm below POI at 100 yards. I was using Sako Gamehead 150g. (Photo: 5 shot group, 1cm square target)

Am I doing it right?

Not based on what you have said. "I dialed the scope 2cm below POI at 100 yards."

If you want to be zeroed for 200yds then your POI needs to be 20mm or 2cm above the POA.

What was your POA in the picture attached? If it was the center of the target then you are zeroed for 200yds but I would come left 1cm

Yes, it was center of the target.

Did not adjust windage because the wind was strong and erratic.

@sheep fair enough mate. Wind should not effect the 308 that much though and at 200 yards your error to the right doubles so I personally would adjust half that to the left .1 mrad and be done with it.

Solid advice re AB if you have the $$, the phone app is about $40 and worth the investment.

Good luck
