That can run from several hundred to several thousand dollars. Just right there you can see why the armchair experts have a problem documenting much of anything. A summons and complaint filed in a civil case may mention the gun or ammunition used. That is a poor legal move, but it can happen. That is NOT evidence, only a complaint and will be addressed in court or depositions, or it won't every show up.
Complaints contain a lot of superfluous information and comments.
Also for such information to impact a jury it will have to impact ALL of the jurors to be very effective. The gun and ammunition concerns are the least of your concerns. You have to worry about the legality of your actions. If bullet choice is that important then we would think the gun rag writers would endorse Full Metal Jacketed bullets. When pressed to tell us which bullet choices are bad they fall pretty flat real fast.
