That video proves nothing other than birdshot had a larger spread... He even said that the birdshot will not penetrate as deep as the buck shot. Look at videos where the birdshot is shot into ballistic gelatin. The FBI states that you will need 12" or more penetration in ballistic gel to reliably hit vitals. Birdshot fails to reach 12" penetration.twomillenium wrote: It is, it has and that is proven

Here is a video using #4 shot... It fails to have sufficient penetration.
