I'll second everything Dick said and will add Remington Express is a NO NO NO Please don't do it !!! Look for vintage low pressure shells like RST, or Polywad. But before you shoot it I would get a DOUBLE GUN SMITH to take the locks off look at the wood and MAKE sure the stock is tight. This will not cost much if you need help with finding a gun smith let us know where you are and I'm sure others that know more than me will chime in. What a great gun you have I love those high ribs.
