Interesting "mythbusters" on thetele rightnow. They are working on the story of Carlos Hathcocks famous counter sniper shot through the opposing snipers scope.They get a winchester" hatchcock replica (available new now).. Lined up at 100yards against a ballistics gel- head behind a scope. All 3 100 yard attempts hit, shatter objective and stop within the scope tube short of the gelhead eyeball. They even try at point blankrange ( just a couple of yards).The bullet tears thetarget scope outta the mounts leaving a ring around the gelhead eyesocket .clearly capable of inflicting injury but the "hathcock throught the eye" results could not be duplicated. I don't know what the ballistics of their round was ;nor did the type of scope used as a target match a vietnam era com-block sniper scope. So the experiment coulda been more exact. But with all the convex glass surfaces to deflect the bullet slightly or just shatter and pile up to absorb the energy.The bullets never penetrated the entire tube. They reluctantly declare "myth busted"..
