This product will be quite a breakthrough for a lot of us long range hunters. A version has been in use in Europe and Africa for some time. But this version is better in a number of ways. This one is made by Rudolph Optics.
It provides an amazing sense of solidness, if that's a word. There is zero left to right wiggle. And you only have to control vertical.
A downhill lie works best...with your feet below your butt. Among other advantages, that allows you to rest your shooting arm elbow on a knee. The rifle is supported from both front and rear.
With more practice from a good ground setup I expect to routinely be able to place shots into 3/4 moa out to 700 yards in no-wind conditions.
Here is a picture of a 3/4 MOA 3 shot group at 455 yards from a sitting position.
And in the 2 last target pictures, the 6 total shots from the 2 separate groups would superimpose with a 1/3 moa vertical spread. I used a tripod jammed under my shooting arm's armpit to stabilize the vertical, the Quad Sticks alone handle the horizontal with zero jiggle. When I am setup this way, I can hold my crosshairs within a 2 inch bullseye at 916 yards.
