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

The true drop at 300 was .ore like 8" but for a body shot at a red deer it was good enough. The height of a scope mount above the bore wil alter the rule numbers considerably.

the rule of three has been posted above......scope sighted rifle with assumtion scope is 1 1/2" above bore.

Attachment 181110

Finally sighted in at 206 yards. First shot closest to bullseye.

Last zeroing at 100 yards, 2 inch below POI.

One click up (mrad) and good to go?
