An expanding solid designed for the largest game. Same point of impact as the 410-400FPS. Bore riding design. Used in the 450/400.

Due to the bore variance of this caliber, please call us if you have an older double. New double rifles from Heym, Merkel, Searcy, Kriegoff, and Ruger #1 have correct bores at .410".

If you have an old double, we can slug it for you, or give us the bore diamter, and we can custom cut the bullets to match your guns bore.
