I want to diagnose a problem I had shooting precision rifle today with a familiar hand load. We've all missed shots due to wind calls, etc. But, I've never missed a shot by this margin before, especially when I KNOW I broke the shot clean.
I often shoot steel plates to 500-600 yards, which is the maximum distance available at my range. Today I was shooting and had one HUGE unexplainable miss on a 600 yard plate. After shooting a 1.5" group of 4 consecutive shots on the 500 yard plate, and two consecutive hits on the 600 yard plate, I watched a third shot at 600 miss the 12" plate by at least 5 mils (that translates to 9 feet or so at that distance).
I've been shooting this load for 3 years with good accuracy and no problems. Even at the 600 yard line I can't think of ever having missed by more than 1 Mil on verified dope. The only recent change to the dope was a brass change, which seems to have increased my velocity a bit, but has still provided good accuracy.
So, what would explain a flyer that misses by such an impressive margin?
Also: The trigger release was good, I'm using a S&B scope, 175grain .308 SMK bullets, and I was able to observe the miss through my scope (as was my spotter through his). We both agreed it was a 5 mil miss.
