Our 45-70 Is Ready To Shoot

This is our favorite 45-70 for light-recoil plinking. Developed with the 1873 “Trapdoor” Springfield in mind, it is a great option for any rifle (or revolver) chambered in 45/70. These projectiles are cast from a softer alloy ideal for the lower pressure and velocity of a proper Trapdoor load.

Why Use 45-70 Trapdoor Ammo?

Our 45-70 Springfield trapdoor bullets are loaded with smokeless powder, and every batch is pressure tested to ensure they do not exceed the limits of older rifles. Not only do we pressure test in a universal receiver, but we also use a Trapdoor rifle to test the velocity and completeness of burn. Because this is an ammo typically used for a vintage firearm, they are widely used for target shooting to experience the feel of an old rifle. If you’re looking to see what it’s like handling an older-style weapon with the bullets that were intended for it, look no further than our trapdoor loads at Steinel Ammo.
