The goodness is not that it is just a boresight system. It is a predictive system. Any system that predicts has to have a point of departure, and for this system, it is the rifle chamber. Once you have boresight, you can add the factors that affect a trajectory and build a zero.I'm referring to the entire system marketed by the website you linked to. Your system appears to be an unnecessarily technical, complicated, and expensive method of sighting in a rifle. And for what? I am aware of no competent marksman who can't get zeroed in a few minutes for price of a handful of rounds. And since your system still requires confirmation by shooting a few rounds, what benefit does it bring for the price?
Absent a hardware problem, if someone can't get on paper and dialed in within a reasonable amount of time (let's say, whatever amount time it takes to unbox your system, read its manual, set it up, and figure it out), then they probably shouldn't be at the range without someone who knows what they are doing. And if that incompetent shooter can't do it the traditional way, what makes you think they can do it when they add the complications of your system to it?
Getting sighted in just doesn't seem to be a problem for anyone I know or have heard of.
Thank you for the feedback!
