Hi all just wondering if someone can help me I was clearing out an old shed of my grand dads and I came across 175 eley four long paper cased shotgun shells and I was just wondering if they were worth selling or just shooting them off they are all still in there full boxes and they are still in there outer box which was originally brought from midland shire farmers so I know they are not too old but old enough thanks Daz
