Yup. But most people will choose to ignore this type of information. I see tons of comments on YT videos about how it's impossible for a 30-06 to hit someone in the neck and not either completely explode someone's head or not pass through or some other nonsense. People don't realize that it depends on so many factors including: type and weight of projectile, powder charge, angle, luck, etc. Most hunters I know don't want to completely destroy the animal they take. So their bullet choice and load is tailored to that. Who knows what type of ammo was in the rifle or how old it was.
I hope the FBI releases that info. Ammo type/brand/load, etc.
