this chrony gizmo is revealing all kinds of interesting factoids. the object of my experimentation is my savage 10 pc in .308. 20" heavy barrel. it was touted by several people i talked to as being super accurate. well, now that i'm rolling my own ammo, it is showing serious potential, BUT, with light loads, and at low velocities. with 168 gr match bthp from sierra or speer, it is sub .5 moa if i keep the velocity right around 2400 fps. the groups open significantly as soon as i get over that velocity. i suspect that the "sweet spot" velocity will change with bullet weight, and that there may be another sweet spot up higher (i did shoot some good groups in hot weather with maximum loads, but i didn't have the chrony then). is this correct?
