Building accurate, consistent ammunition starts with quality components, and Speer Bullets .243 caliber 6mm 100 grain spitzer boat tail rounds are built for reloaders who demand precision. Whether you're handloading for varmint hunting, target practice, or precision rifle competition, these jacketed rifle bullets deliver the dependability Speer has built over seven decades. The boat tail design and spitzer profile work together to stabilize flight and group shots tight—exactly what you need when you're the one controlling every variable in the cartridge.
The .243 Winchester (6mm) is one of the most versatile cartridges in North America, equally at home on prairie dogs, deer, or the range.

The profiled jacket is engineered for optimum ballistic characteristics, so each bullet flies true downrange. A 100-grain bullet in this caliber hits the sweet spot for hunters who want effective energy delivery without excessive recoil, and for reloaders who want proven, forgiving performance.
You get 100 bullets per box—enough to load a solid batch of hunting or practice ammo without breaking the bank. If you're new to handloading .243, Speer bullets are a no-fuss choice backed by decades of shooter feedback.
