Has anyone had experiance with this model Benelli w/ the Undertaker choke tube?? I tried to patter this AM with factory choke was not real happy with my results. I used several different brands and loads but could not get anything consistant! But,also had my 13 year old sons Rem 870 youthalong along with the Undertaker choke with #6 Rem Hevi and it was very consitant outto 35+ yds.Any help would be appriciated.

Thanks!!
