I've heard the Gunwerks G7 system is pretty good. It collects real time data to calculate a ballistic solution based on hard data that you input prior to the shot. level 2
Oct 01, 2003 · The validation experiments showed that this system was both robust and reliable and should be able to manage a radius of curvature less than 200 mm. In the pre‐scanning mode, a radius of curvature down to 2 mm was managed for pipe intersections at 3 scans/mm, using a laser scanner with an accuracy of 0.015 mm.
