I think this sonic barrier is something that we creep up on and as we near the speed of sound at whatever your conditions are, whatever the speed of sound actually is in your location, things start happening...air flow changes down the side of this stubby lil-pill, drag on the rear changes & I think these things are more disturbing to it's flight than it is to a long 'cruise missile' the center-fire boys relate to.
Think about it...all the pictures of projectile flight do not include our stubby lil-pills...all the experimentation I can find is done on larger & heavier & longer projectiles up to and including cannon-fire.
The effect I think it is having on my work here amounts to the width of a projectile .224" or thereabouts...that's why I was wondering about why the projectile seems to dance around inside the 10 ring as I shoot in near perfect conditions and am getting near perfect releases.
