[QUOTE="Len Backus, post: 30105, member: 1"] Jeff Can you proffer a guess as to how much accuracy is gained from the sorting you describe? Yes, I would like to see a picture of your trimming device. Chris Good point. At 3150 fps and bc of .750 the wind drift (10MPH) difference with a 50 fps variance is about 1 inch at 1K. At the same time the drop difference would be about 7 inches. Add to these Jeff's effective .020 bc difference and you get an additional 2 inches of POI deviation. [/QUOTE]
