At one point I heard the gun was an M4 which would be an AR 15 5.56mm projectile, which tumbles, right?
Both my brother, and my brother-in-law had serious hip injuries, both requiring hardware, screws, plates, etc.
Both were in their 20s at the time, and returned to near complete levels of activity. My brother cycled 100 miles, and ran 1/2 marathons (13 miles).
Both of their injuries involved mostly bones, not projectiles, damaging organs and major soft tissues.
The doctor that gave the presser yesterday, stated he felt Scalise would walk, and maybe run. Good news.
