Wanted to find a choke that would shoot both lead/Hevi well. I believe I have found it.
Federal Strut Shok # 5s

Federal Grand Slam #5s

Federal Strut Shok#6s

Hevi #6s

Before trying this choke I had been shooting a .690 JellyHead that would do better with the Hevi6s but no where as good with any of the lead.
