[QUOTE="entoptics, post: 1705573, member: 104268"] Below is last year's hunting practice plotted on a generic deer picture.[ATTACH=full]148075[/ATTACH] Might be hard to see, but there's a green dot at the center of the vitals, and I measured the distance from the center of the target for each shot, and scaled the image to a real deer, and plotted those hit locations. The numbers are kinda hard to see, but they vary from 300 to 573 yds. All shots were recorded over a month's time, and were true cold bore shots, "hurried" (1 minute to unsling, setup, range, and fire), but from an "excellent field position" on a bipod and rear rest (backpack, little shooting bag, binos case, etc). 1) Precision - Hard to quantify since the distance varies from shot to shot, but the group measures just under 10" across, so at max distance of 573 that's 1.6 MOA, and minus the one nasty flier in red, it's 1.2 MOA. 2) Accuracy Pt 1 - For some reason, my overall group was ~1 radius low, despite what I thought was a near perfect zero, and well established ballistic profile for the load. 13/16 shots would also have been clean kills, with 1 marginal and 2 misses (likely fatal, but still not clean). 3) Accuracy Pt 2 - Where I shoot, the wind almost always blows roughly west to east. You can see my group is barely favoring to the right, and all three marginal/misses were far right, so I clearly was underestimating windage in several cases. I highly recommend this type of exercise. It was good practice, and gave me some eye opening results, which truly helped me make adjustments for better odds against real game in real conditions. IMO, for most hunters with limited time and/or budget, this sort of thing is far more important than fiddling around trying to shave a 1/4 MOA off of precision by finding a "node" or tweaking action screw torque. In my case, my [I]accuracy[/I] was a factor of two worse than my [I]precision[/I] [/QUOTE]
