Two items at the range:
First, having a whole bay to myself is fabulous. For the second time, I setup my Chrony and recorded dozens of shots. It has worked flawlessly outdoors. Indoors I had issues getting the light right. This is great.
Secondly, while on the 100yd multi-user range, there was a guy practicing position shooting. Had the stiff leather jacket and glove, matt everything. I took a break and wandered down to see what he was doing. He had the neatest gear. ($1,600 neat)
This was a small tubular camera with accelerometer that clamped on his barrel and has a USB cable to his laptop. What it does is, after the shot, replay the aiming wiggle. It highlights the last hundred or so milliseconds to show trigger let off. This isn't a camera that shows you where your shot went, but how it got there. Wish I had gotten the name of the company. They have a less expensive dry fire version as well. Can be used on pistols as well. For the very serious target shooter. BTB, his aiming hold, prone, was less than 2MOA. On a 20 shot, 200yard, National Match target he had all 10's. AR-15 w/ standard iron sights.
