For OBT, here is the muzzle disturbance vs time with the sound wave impact. Note the
multiple reflections. Amplitudes are constant as he did not model any energy losses.
expanded view of 1 set of impacts.
Mr. Long was going for ultimate accuracy and timed the bullet exit
at the flat portion of the curve, just before 1.25mSec with the idea being
that for small changes in barrel time, say between 1.2 and 1.26mSec, there
is no change in muzzle disturbance.
For me, since only interested in hunting, I time my bullet exit half way between
the muzzle disturbances, i.e. 1.1875mSec. Yes, with natural reload variations,
the bullet exit will encounter more or less disturbance, but in this area, it is almost
2 orders of magnitude less than if the bullet exits at the sound wave impact!
