Originally a black powder cartridge, this is basically a .44-40 necked down to accept a .401" diameter bullet. Our .38-40 brass has a wall thickness of .0062" but is still stiffer and less fragile than other brands which make it much easier to reload.

I have been loading Starline 38-40 brass for 15 years. I may still have some of the original brass. That's how good it is.

I have been reloading for 40 years , when I started using your brass I was very happy with it . Your 38/40 brass is far superior to other brands that I have tried. Thank for a great product
