308Nut Report post Posted May 21, 2010 Now I remember why I live here. After a looong cold dark snowy winter, I was able to get up to my shooting spot. It was an absolute gorgeous day. 50-60 degrees, blue sky, soft breeze...........Anyway, despite making not one but TWO mistakes, I remembered why I get out and practice so much. The last thing I want to do is make a bad hit on a critter or have the trophy of my life get away. #1: I forgot my hand held ballistic calculator on my desk at work. Duh! #2: Because I didnt have my calculator, I defered to a printed drop chart I printed a month ago (which of course is NOT calibrated for the temp or altitude I was shooting) and promptly read the bullet drop for 725 yards in the WRONG column. I dialed 20.5 MOA and let her rip. This led to 2 bullets wasted as they flew over the target somewhere in the neighborhood of 61.5 inches. I knew I should have listened to that inner voice that said "isnt 20.5 MOA a bit high?" Duh! Anyway, I was so excited that it was such a nice day that I just was not very carefull. After seeing that I missed the target clean, I went over the chart again and saw where I went wrong. After correcting to 12.0 MOA, two 338 rounds went in the target. Not the best group but acceptable. Next was the 308's turn. After dialing the correct drop this time (at least correct for the temp and altitude in the paper) of 4.6 Mils a nice and tidy 3.25" 3 shot group resulted right at 6.5" high (altitude and temp) I dropped it down to 4.3 Mils and viola. 2 in the orange and one a bit lower for a 5" 3 shot group. Then I set up at 300 yards to verify my zero. 3 190 grain pills landed perfectly in a nice tidy group. Note to self, ALWAYS have the right equipment handy!! Regards and happy shooting this summer! The first 725 yard 308 3 shot group 6.5 inches high The second group 300 yard zero verification (The 2 bullets in the black are from the 338 at 725 yards) Share this post Link to post Share on other sites
