One of Ideal’s earlier designs, the 3118 (later renamed 311008) was designed as a ‘standard’ bullet for the 32-20 Winchester cartridge. The bullet weighs 118 grains in lyman #2 alloy. I’ve used the bullet in the .32 S&W long, .32 H&R magnum and .327 as well as the 32-20. It also works as a lightweight bullet in the .30 caliber rifles as well.
Available in either standard alloy and sized .308-.313
