Yea you can't go wrong with Winchester Xpert shells. We bought Hevi Metal shells last season and I wasn't impressed at all!!!! So this year we went back to the Winchester shells. They always go bang and they will kill just as far as all the others. I personally like 2 shot for ducks. I use a Kicks High Flyer Full choke in my shotgun. That thing will rip em up....no complaints at all with that choke. Good luck opening day man i'll be out there shooting some ducks too. What area you going to be hunting?
If it flies it dies!!!
