  • This is a mold for producing .451 diameter round balls, so it is purpose-built for that specific muzzleloader use case rather than general-purpose casting.
  • The product information does not include load data; the description directs users to consult the muzzle loader owner’s manual or a powder manufacturer’s website before use.
  • Handles are included, but no other accessory or setup details are provided, so buyers should verify what additional casting equipment they already have on hand.
  • The listed ball weight is 137.71 grains, which may or may not align with a particular firearm’s recommended load requirements.
