Since .32-40 brass is almost impossible to find, and really expensive when you do, these are formed from .30-30 brass, so will have a .30-30 headstamp, and be very slightly shorter than a factory brass .32-40. As the case headspaces on the rim, this was not an issue in our test rifle. The cast bullet used is 2% tin and 92% lead with a Brinell hardness of 15.
Loaded to lower pressures, but they are still smokeless cartridges. They performed very well in our Model 1894 Winchester built in 1910 - but have your rifle checked by a professional gunsmith to be sure. 170 Grain lead bullet, available in both cast lead with the traditional lube and polymer-coated - Box of 20.
