I have the same gun and I was going to p/up a box of them to pattern this weekend.I use the factory full turkey choke that I believe is called the ulti-mag full. Does anyone know what the diameter is. I have been using the same loads since I got the gun and have always liked the result but haven't patterned it against any other loads (due to cost). I don't want to buy a new choke so if anyone with this combo can sheds some light for us I would appreciate it. I dropped a bird at 51 steps last year with my current setup and yesterday put around 15 pellets in the head and neck area of a target at 40 yrds. Is it even worth buying a box of Federals and trying them.
