Some folks cleans n service a gun prior to range use. I have never really had an issue w my 870 functioning but after pattern testing, I did take it apart and the gun was as dry as a bone.
You can polish bolt group, rails etc., and this will help the gun cycle. Armorers have done the steel wool trick to polish chambers but the chamber is not always the culprit.
Yet, some guns & people need a break in period.
