When 240 grains is not the load you came to build

Many .429 component listings cluster around conventional 240-grain handgun bullets. A handloader building at the heavy end of the .44-caliber spectrum needs a different starting point: a true 300-grain component with a broad flat nose and a construction identity that is easy to understand.

The 300-grain Gold Country Rhino anchors the heavy end of the Rhino weight progression. It gives the handloader a purpose-built alternative to the 240-, 245- and 265-grain choices.

This listing is for 50 component bullets. Cases, primers, powder and load data are not included. The bullets are hand swaged in small batches, made to order and normally ship within seven business days.

Heavy is a system decision

A 300-grain bullet changes seating, case capacity, pressure, velocity, recoil and firearm function. Its mass and wide-flat-nose geometry do not guarantee penetration, accuracy, feeding or a particular hunting result. Those outcomes depend on the complete load, firearm and conditions.
