Thanks, makes sense.Yes, and yes. It's simply comparative, not real world. It really is only defined at an impact velocity. Most LE trained "firearms experts" opposite of me use muzzle velocity. If my client is so inclined, pretty easy to get them excluded under Daubert for common and simple mistakes.
Got it. Are my calculations right though? We came up with 2 very different numbers for SD.There is actually a program i use. SD changes as the bullet expands, weight/dia sq, the expanding bullet dia is getting larger, weight is the same. Why its really a metric for solids, not expanding bullets, but its still relative. Drive identical weight bullets the same vel, the larger expanding bullet penetrates less.
I assumed this was a 10mm round.
