I'm waiting to see the targets from 50', 50 yards and 100 yards. I like what these tools are able to do, but from everything I've seen in accurizing of firearms, there are items like chamber, rifling and crown, and ammunition is based on ignition, powder charge, bullet weight, crimp (or lack there of), and headspace. I even saw an experiment where they compared issues with the point to issues with the tail: The nipped and ground the daylights out of the point with minimal affect, but a small file cut on one side of the tail and they had fliers every time from every gun.
