Hello, recently inherited a S&W 32 Cal. Lemon Squeezer, ser. # 226116. I has 5 rounds in it that are so old, I'm afraid to fire them. Ammo has been in short supply but I found some at Outdoor Limited. Bought a box but they will not fit, the base of the shells have larger diameter than the older shells. Can anyone reccommend a sourse ot ammo that will fit thos old pistol? Thanks.
