I have a Beretta AL390. It is a NWTF gun. It came with 4 chokes. The 3 usual chokes plus an extended turkey choke. It really didn't pattern as well at longer ranges as I thought it should. I have tried different loads as well as changing from the extended full to the regular full. The thing that gets me is that there isn't much difference between the pattern with the extended or the regular full. I am considering purchasing one of the speciality ported chokes made specifically for turkeys. I was just wondering if any of you use these chokes and if they will make enough difference to justify the price?
