The two on the outside don't show a lack of expansion, I think it shows a lack of petal retention. I can't think you at a speed of 2600 youd really lose your pedals unless some bone was involved on impact. If they're losing pedals at 2600 and soft tissue that would be a little scary.
It would sure be great to have those other bullets that went off into Mysteryland to compare and see how they fared.
Easy to check by weighing.
