My friend (who is a physicist) and I revisited the alleged bullet incident that got steel targets beyond 100yds banned at Kokohead, and needless to say that it's still not looking good for those who claim that a bullet defied the laws of physics and traveled from the range through someone's window, approximately 1.5mi away.
We utilized the ballistics of a 7.62x54Rround and a mosin nagant, given the projectile showcased during the investigation appears to be a be a 7.62. We were initially going to analyze all common 7.62 platforms (AK, SKS, etc), but determined it would be a waste of time, given the low FPS, muzzle velocity and maximum range of those platforms, and that only a platform like the mosin and the 7.62x54R or something similar has the capability to generate the necessary velocity and flight pattern to recreate the incident.
We will be finalizing the calculations next week, but preliminary assessment reveals that someone would need to have walked passed the roof of the bench and into the grass, then fired a projectile at an 89 degree angle over the top of Kokohead, just to reach the location of where the bullet landed. That means someone would have to walk onto the firing lane while it was hot without the range officers noticing, and shoot almost straight into the air. This does not take into account air and wind resistance (which is prevalent at Kokohead), nor the dispersal of kinetic energy into a Target or off the ground or berm, which people claim was responsible for ricocheting the bullet over the top of Kokohead.
I'm not sure if anyone would be willing or want to do anything with this, but it would seem that this information might be useful in convincing those in charge of the range (specifically Mike) to allow the reimplementation of targets past 100yds.
