Thread: Truing a Ballistic Calculator

Hello

I've cronied my load and zeroed the rifle (at 100M). I've shot it at 300Y and 600Y. I've checked I've got the settings in Stelok right.

But the "corrected" drops in the calculator still don't match up, I think corrected I should be 13 clicks at 300Y but Strelok is saying 16.

Is there a good tutorial I can read or watch on this stuff??
