To the less than technologically savy shooter, or to the non-shooter, I'm sure this appears to be a viable idea. It simply is not - not in any way, shape, or form. This is just another snake oil salesman. I'm not sure what his motives may be, but rest assured, what he demonstrates in this video is impossible for a number of very, very simple reasons.

For this to work, the "system" must be able to either affect the bullet in flight or it must be able to re-align the barrel to make up for the shooter's poor aim. This sytem, as shown, has no way to do either of those things.

Once a bullet leaves the muzzle of a conventional firearm, it's on it's own. It is then subject to atmospheric conditions of wind and humidity, but no longer subject to any influence from the firearm that launched it.

Conventional firearms have barrels fixed rigidly to their receivers, which in turn are fixed rigidly to their stocks. The shooter is the interface between the optics and the muzzle, the one who decides where that barrel is pointing when the trigger is pulled. If the trigger is pulled when the optics show the rifle to be aligned off-target as shown in this video, there must be some sort of mechanical interface between the optics and the barrel that will re-align the barrel with the target before the bullet is released.

Even beyond that, if one must "identify" one's target with one pull of a trigger, or press of a button, or whatever it is - while the crosshairs or dot are properly aligned on the target - then go back again and pull the trigger once it is re-aligned, what good is that?

And, even beyond all of that, any experienced long range shooter will tell you that the afore mentioned atmospheric conditions are the real "meat and potatoes" of long range shooting. Bullet drift is a function of the cross wind component of any given wind and the deceleration of the bullet in flight. Bullet drop is a function altitude density, or humidity, plus the headwind or tailwind component of any given wind, along with that deceleration. To make matters worse, none of this will be constant over any given patch of real estate. The wind at 100 yards, much less 1,000 yards, can (and most likely will) be different than it is at the firing point, and it can change multiple times between as well. Let's not forget updrafts and downdrafts due to intervening terrain, either. All have very dramatic affect on the path of the bullet.

Just for fun, anyone care to guess what the wind drift at 1,000 yards for the .338 Lapua shown in the video might be, say for the very simplest of cross wind conditions? How about, say, a steady, down the entire range, 10 mph cross wind? For those who would like to calculate it (or look it up), assume a 250 grain bullet with a ballistic coefficient of, say, a very generous .600, and a muzzle velocity of 3,000 fps. You might be surprised...

Anyway, until this gee-wiz device can compensate for all of that, it will remain just so much snake oil for the easily impressed.
