in most trials, the crime labs are always able to take a bullet from a crime, and determine the caliber, and the bore diameter and the depth of grooves.
However when i wanted to slug the barrel on my rifle, i suggested to several gunsmiths if it would be ok to simply load a roundball up with a super light low velocity load and simply shoot it into a bucket of water lined with bubble wrap to prevent any barrel damage from misuse of rod while pushing a slug down teh barrel in the conventional slugging method.
the gunsmiths told me that even if i used asuper light squib load to push it out into water or an old feather pillow, that the round ball would have so much velocity that the measurements taken would be 100% inaccurate considering my barrels bore as the impact at even such low velocity would mash the bullet beyond usefulness.
So i would like some kind of legal aspect on that if a projectile moving under low velocity is unusable to take accurate measurments of your barrel, then how can the state crime labs even identify the caliber of a fired round, or to even match a fired bullet with a particular gun.
logica train... if velocity+impact of projectile= projectile that cant be used for slugging a barrel
if measurements wont equal barrel how can it be compared to a lead pellet pushed by rod through a barrel to slug it to create a comparison?
better yet, if impact at any velocity alters teh bullet, how can the lab say that shooting a different bullet into a different test medium (water tank or rubber media) be assumed to create the same deformation of the bullet?
