We've all heard the rumors that the old 1:12 twist AR15's and M16's using M193 ball delivered vicious wounds to soft tissue. We have also heard the rumors that the new 1:7 twist rifles with heavier ball rounds like the M855 don't cause the same damage. So, we put together a little non-scientific test to see if we could document a difference.

If you carry a gun for personal defense, you need to be protected from lawsuits or criminal charges should you need to use your firearm defensively. I recommend USCCA: https://tracking.deltadefense.com/aff_c?offer_id=94&aff_id=18652
