I have a 1919 Elsie Featherweight in 12 ga. with two sets of barrels - it is a specialty grade. Have been shootng a little skeet with the 26 inch barrels choked imp cyl and mod. Just went hunting with it for the first time Friday - north FL. quail and used polywad's Vintager Doublewides with 7/8 oz. of #8's. Very effective and I recommend them if they have them in 20 ga. These shells have their spreader disks in them to enlarge the pattern and work very well. In any case, shoot the gun, don't worry about the value or changing it and just enjoy your classic.
