FAQs

Q: Why use .427" instead of .429"?
Some cartridges like .44-40 and older firearms have smaller groove diameters, making .427" a better fit for:

  • Improved sealing
  • Reduced leading
  • Better accuracy

Q: Can I use this for .44 Magnum?
Typically no. Most .44 Magnum firearms require .429"–.430" bullets. Using .427" may result in poor accuracy and gas blow-by.

Q: Do I need to lubricate bullets before sizing?
Yes, for cast bullets. Powder-coated bullets may not require additional lubrication.

Q: Will this improve accuracy?
Yes—correct bullet diameter is essential for consistent performance and tight groupings.

Q: Will it fit my press?
Yes, it fits all standard reloading presses with 7/8"-14 threads.
