FAQs

Q: Why choose .451" instead of .452" for .45 ACP?
.452" is standard, but .451" can:

  • Improve feeding in tight chambers
  • Help pass the plunk test more easily
  • Reduce chamber pressure slightly (in some setups)

Q: Will .451" reduce accuracy?
It can in some barrels if the bullet becomes too small for proper bore seal. Best results depend on your barrel’s groove diameter.

Q: Can I use this for revolvers like .45 Colt?
Generally no—revolvers typically perform better with .452"–.454" bullets.

Q: Do I need to lubricate bullets before sizing?
Yes, unless using powder-coated bullets.

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