Consider a BT99 hardcase and trim the center barrel support and expand the rear lug support block. I did this easily and now my one case will hold my 32" BT99, 34" BT99 Pigeon, 30" Superposed Trap and/or my 32" Citori 425 Sporting. Nice thing about BT99 case is that it will hold up to 34" barrels.
Mods are easy, but most Browning hardcases are limited to 30"s
