AZAV8ER Report post Posted Monday at 03:41 PM For years hunted with a 30-06 and fixed 6X Leupold and made shots from 40 yards to 380 yards. I figured out the measurement from the center of the cross hairs down to where the duplex post gets thicker. Knowing that measurement you can range deer or elk and also use the point where the duplex goes from thick to thin as a 400 yard hold on my setup. Did it for the simplicity and figured less moving parts equals better reliability. Share this post Link to post Share on other sites
