The big girl was feeling neglected sitting in the gun vault, so I took her out for a little run today. .510 AM NF NXS 8-32X56 750 grain Amax @ 2700 fps. AR50 platform These first two pics are my bench........ it's not much to look at, but it is solid! This is a look down my range. The first target is at 100, the second at 300. You can just see a dark spot in the gap at the far trees at the base of the hill. That is my 1000 yard gong. The 300 yard target stand was repositioned to 1000 for the shots in the pics. I don't shoot the gong with the 50, been there done that and had re-weld my chains on after it knocked it about 3 feet off the posts. This is the second group shot at 1000. It measures 1.5" for 3 shots. I only had a light wind but the mirage was pretty bad. I got off the these 3 shots when the wind was practialy 0 and mirage was minimal. The upper group measures 4.5" for 4 shots. It is still under 1/2 moa. The wind was not enough to push those big 750s around but the mirage was pretty bad when that group was fired. It's been a while since I shot the big girl and I had almost forgot what she is capable of............ Hats of to Kirby for buidling such a great shooter.
