[QUOTE="Kennibear, post: 888364, member: 51650"] WOW!!! Ohler makes an acoustical target that works only on supersonic bullets. I do not know if it can distinguish to the finesse required for this. It could be set up to record the accuracy at multiple ranges of the bullet's path. As soon as the bullet strikes a solid target, no matter how thin, the bullet will be deflected. You cannot meaningfully shoot through multiple solid targets,even very ethereal ones, for accuracy comparisons. Unless I am visualizing this wrong, the assumption is the wobble of the bullet is damped out at some undetermined range and continues on its merry way at the lowest Cd of that particular shot. That is; at some point the bullet settles into its best low drag configuration. Correct? In the world according to Kennibear here are my assumptions: 1) The bullets are traveling along a theoretical average path. 2) Wobble (Redneck for yaw and pitch) cause bullets to diverge from said theoretical path. 3) Yaw diverts the bullets in one plane in two possible directions and pitch diverts the bullets in a perpendicular plane to yaw in two possible directions. 4) There are no "perfect" shots and each individual shot will wobble somewhat. 5) Wobbles are snowflakes, no two the same. 6) Each shot will enter an actual bullet path divergent from the theoretical consistent with its wobble and stabilize in a path (Cease Divergence) at the point where the bullet goes to sleep. 7) From the bullet's "nappy time" place along its path it will continue at that divergent axial value from the theoretical until impact. Conclusion: When we shoot a group of say five bullets they will diverge (i.e. accuracy will suffer) until they "go to sleep". I doubt "nappy time" is at the same place in the path for every bullet. But from that point they will each travel along a path at relatively fixed distance from the theoretical. Therefore we would observe the MOA group size increase until "nappy time" is reached and the actual measurement of the group (in inches) remains fixed as the range increases which appears as decreasing MOA. Unless the divergence of the path imposed by the wobble includes a significant angular component, at which point the accuracy looks like every group my poor eyesight and caffeine hammered nerves have ever shot.
