Symmetry is the key on the base . I'd say your buddy did what he did in a very get lucky way . The nose on the other hand ....... It can suffer some pretty extreme damage and still fly straight . There was a nose damage demonstration video with 22 LR . The guy actually cut half the nose out a dia or so down . Strangely it would shoot groups but the expanding spiral ensured they weren't where you were aiming .
North American Hunting did a video long ago where they mangled noses and bases of Nosler bullets for the demonstration . A notch in a boatail base will ,in their demo, cause it to deflect because of uneven gas escape across the base .
I would imagine that at some point in reduced muzzle pressure , where the gas push drops below 25% of acceleration maybe , base quality may become a nil point .
With all of this it begs the question from the "everything we know is wrong file" . How the heck do we shoot little bitty groups with 22 LR with those swaged healed bullets crimped in cases manufactured on lines producing millions per week with more or less 1840 tech ?
