I've got 2nd Focal plane Mil Dot scopes. I understand the Mil dots are for ranging. Also their calibrated for a specific power 12X On a FFP plane can I aim with the dots ave various ranges. Say my rifle is sighted in for a 100yds and I see a coyote at 300 yds. Can I aim the 2nd or 3rd dot on it and hit ?On my SFF scope I can't 3rd dot at 300 yds could cause me to shoot way over the top. Allowing the yote to howl another day !
