ATF ballistics expert Samantha Carner testified the one usable bullet fragment — labeled 6A — had a diameter range of .286 to .301 inches. Tyler Robinson's .30-06 rifle fires bullets starting at .308 inches. The fragment is too small. Three of the seven fragments extracted from Charlie Kirk's body were never delivered to the ATF. One of the four that arrived was labeled as evidence, and even that doesn't match the alleged murder weapon.
