After reading about the Trulock choke made for the Fed HW #7, and talking to George Trulock I had to give his choke a test ride. And the 100% money back if you are not happy also helped.
My gun is a 11-87 sps-t with a 21" barrel that has been cleaned. The first shot was at 40 yds. The paper I shoot at is 23" wide and 41" long. For some odd reason my POI was left several inches. I will hunt this combo if I can get the POI corrected. ( I shoot with the standard rem beads)
The second shot was with the the Fed HW #6 shot, and it knocked over my backer when the shot impacted.
The range was 27 yds.
