A number of years ago I came across many old "Ideal" single cavity molds at a gun shop. Apparently the shop owner bought out a widow's husband's belongings. These are old world quality and I bought 7 of them @ $20 each. They are a dream to cast with and produce first class bullets. The molds were: 311281, 311284, 311467, 311413, 308334, 308291, 266469 and Dr. Hudson's 319273. I feel lucky to have them! Bud
