We did have a string of fascinating folks visit our booth: Accu-Shot is a "better mousetrap" that just about all serious shooters are buying. Just a little 6oz, $68 gizmo that replaces and far outperforms your old sandback under the butt of your rifle....
One old fellow (no BS) is into 2 mile shooting with his own .408 wildcat. You had to be there. He says you need a table for the earth's coriollis effect.... No kidding, he was the real deal.
We also had CIA, IDF (a female major sniper leader no less), USSS, guys from foreign teams, SF, you name it. The little hand turned up-down micrometer in the back is the only way to go, it seems like. Chuck out that sandbag!
I didn't mention the 2 mile shooter to the USSS guys when they were in the booth. It might have given them heart attacks.
Stay Safe !
