Thank you. I guess my problem lies somewhere else. I'm still trying to figure out why my pattern is all over the place.
I have found that there are 2 first steps to take when having patterning problems with 870s.
The first is to "deep clean" the bore. The second is to make sure that that the magazine cap is tight. If that cap is not tight your barrel can move in the receiver itself and cause a scattering of the shot.
I recommend that you tighten as tight as you can by hand and then give it 3-4 "clicks" with some padded pliers.
Many times those 2 actions can cure the erratic patterns that are sometimes seen with 870s.
Lastly, do you still have the original barrel for your 870?
Thanks,
Clark
If you need help with the "deep cleaning" please let me know.
