I have a Browning a-5 magnum that hates federal shells and jams with anything less than 3 inch magnums.I know the gun is clean and seems to be in proper working order.I have to shoot it with one friction ring for steel shot and it still jams with 2 3/4 inch shells.If this gun isn't cleaned inside and out after every trip it will jam .Not that i mind cleaning a gun .. just hate listening to my brother in law bitch because my gun always jams up at the end of the day .When i clean the gun I spray the action out with gun scrubber and give everything a light coat of rem oil and wipe most off with a clean cloth .Any ideas would be appreciated.
