I am curious if it reduces yaw variables as well past 600 yards.
Dimpling would result in a loss of chamber pressure and energy efficiency from gas escaping between the dimples and grooves of the rifling. I think your head is in the right place, but basic pv=nrt will demand a sabot design to accommodate a dimpled bullet.How long before Mr Tubbs has a dimpling tool?
If we could dimple the surface or nose/tip it would increase the bc.
Yes, it is interesting to see the parallels. I still recall the first time I saw a rimfire barrel tuning system. It was on a Mossberg Model 46 (circa 1937), where the front sling swivel was attached to a metal barrel band (that wrapped around the barrel and was threaded for the sling swivel screw) via a tensioning sling swivel screw. You just tightened the barrel band by turning the swivel, and the barrel band tightened to adjust the harmonics of the barrel to be optimum for the ammunition being used.
Hard to believe that concept is coming up on a hundred years old now... Oh the ironies of cyclical technology development.
Where can you buy the nose ring tool from?
Aerodynamics at high speed (just like fluid dynamics) is such an interesting ever changing subject that seems to always disprove previously cherished ideas about how to make airflow faster or smoother. It's an amazing area to study.
