This is a an early 90's 870 youth 21" barrel that I put a Hogue stock set and a Bass Pro Blackout 575 choke on it which is made by Carlson. I tried Federal Heavyweight 7's, Hevi shot magblend 5,6,7, and Winchester Long Beard XR #6. Also, tried Winchester Supreme #5 which was laughable unfortunately. The HW and Magblend shot almost identically, but the magblend wasn't quite as even a pattern out of this choke. I was really impressed with the heavyweight AND the lead LBXR load. Either load would've taken the head off last years bird at 20 yards! One thing is for sure I will be investing in adjustable sights next season instead of a Hi viz bead. Not completely awesome results, but it will work.
