I will be real surprised if that does not work. FWIW, my daughter's 870 youth with 3" HW #7 is perfect at 30 and spotty at 40 with just a Remington Full choke (she is a new shooter, so I don't want it real tight). I am going to limit her to 30 yards. I have a Trulock Fed HW choke I am gonna shoot in it this weekend (Florida here) to see how it looks at 40 (that is so I can use it too).
