Sierra 6mm .243 Bullets

Sierra 6mm component bullets, .243 inch diameter, sold as a handloading component rather than loaded ammunition.

6mm bullets cover a wide spread of cartridges, from the older 243 Winchester up through the newer 6mm cases, and what usually decides the fit is bullet weight and length rather than the case itself. Match the bullet on hand to the load data you are working from, and check the markings on the box before you seat a round.
