I had one back in the mid 90's. First off mine kicked like mad Missouri mule. At the time there was not much if any HTL loads. I tried Win. 2.25oz #5 and #6, and Fed. #5 and #6 3" and 3.5". It shot fair not great. I used it as my rainy day gun a few years then sold the gun to someone that wanted it more than me. I don't remember the pattern numbers but I do remember that mt 870 with 3" 2oz #6's shot way better and I didn't need to put my arm in a sling after i shot it. I agree with SumToy tho i bet the Fed. FCW might be very good with the old mule "that was what i named mine". Good luck, you might wanna invest in a lead sled.
