Morneault

I've got a year-old Montefeltro. I've run hundreds of Herter shells through it with no problem. I ran out of Herter's and started using Winchesters and the eject problem started. Traded for a box or Herter's and the problem went away. Starting shooting Winchesters and the problem came back immediately. Leads me to believe it may be shell related. I also ran a couple of boxes of Fiocchi when the gun was new with no problems. I've just purchased some Federal shells and will see what transpires with them. All shells mentioned were 7 1/2 or 8 shot, 2 3/4" shells. The only real difference is that the Winchesters were "Heavy Lead Load".
