If he's shooting a Winchester gun, I could all but guarantee what they would recommend...Winchester Supreme Extended Range. Their priciest shells. They are some pretty good shells, though. I got decent patterns out of them...when I patterned for my gun they came in 4th...behind 1)Rem Wingmaster HD # 6's, 2) Hevi-13 # 7's, 3) Hevi-13 # 6's. They all patterned better than the lead loads I tried out.
