Re: Benelli M4 ammo?
I've run with the factory choke through several brands without problem. Haven't had a problem with Federal or Hornady slugs. Most of the time, I've shot the Mil surplus Winchester OO buck, which I got when Midway USA had their sale (which I realize is not much help right now). I still check with them to see what they've got, as they seem to have as much as anyone.
