Shotgun Gate Part Deux

I promise that this will be the last shotgun gate post until the next one...

Via Geek with a .45, some science nerds are looking at 28 gauge shot patterns from various ranges. They start with patterning boards and move to chickens, etc. It is an interesting post and they have great pictures.

The problem is that we don't know what choke Cheney was using and the choke can have a huge effect on pattern size. The guys at My Science Project guessed modified which is probably the best choice. But if Cheney was shooting full, I expect the pattern to be significantly different.
