So I see a lot of 5.56 SBRs, some with REALLY short barrels, and I have to wonder, how do these short barrels affect terminal ballistics? At what point, if any, would 9mm SBRs become more effective?
Here (http://ammo.ar15.com/ammo/project/term_fragrange.html) is some info on military 5.56 ammo. I wonder how commercial self defense rounds are affected?
