This post is designed to give us a "floating" repository of shotgun and ammunition performance. The intent is that we have data available for members to browse.
The criteria is pretty straight forward. Your shotgun by model, choke, load, distance, pattern.
I thought hard about this, as both Erick and myself strongly suggest that you pattern your gun and load. What we don't want is for someone to assume that their performance will match, you have to test it. That being said, this posting should give folks a baseline for purchases and decisions.
