I broke it down completely and cleaned with solvent. I then applied a light coat of rem oil and wiped with a rag. i am going to try again today and see what happens. i think you might be on to something with heavier loads. Thanks!!
Last year I bought a 20 ga. M2 in camo finish. I used it last year for ducks and geese, no problem. This year, I tried to use on doves, but i had a problem with the second shell not cycling into the barrel. any suggestions??
