They are all different but I shoot a dedicated 870, SPS, undertaker choke and Winchester Supreme(black box) 2oz #6, 3.5". When sighting in I will warn you I have only been able to a max of 5 in one sitting and bruised to boot. They are brutal, you will be told the 3.5 is not needed, but they will kill turkey's very dead to 54 yds. Just be aware my gun shoots a golf ball sized pattern to about 17 yds so aim where the feathers meet the skin on the close ones
