This weekend I took two days of training from a Marine sniper who served in Afghanistan. This guy is GOOD. but he is 34 and I am 84. There is a big difference!!! But he was able to take me from 50yds to 955yds in two days. I had never fired a 6.5CM. Sun afternoon I was consistently hitting 10" plates at 955yds. Thats not brag, that is comment on a great instructor. He taught me the reading of mirage....its Zen. Intelect cant do it , just hooked my eyes directly to my brain and I could do it consistently, but if I tried to "think" it, I couldnt see it. Fired 60 rounds with only one early miss...until the barrel hit break in and I had two high shots as the barrel sped up. Paul then tried two and they were both high so we re zeroed and went on. It was a GREAT weekend with an awesome instructor. Just wish we had been able to shoot my new Lapua 338 Mag but the scope mounts didnt come in time.
