A long forgotten cartridge from the BP era of the 1870s, the 38WCF stubbornly hung on into the smokeless era. I'm enjoying this cartridge chambered in my 1902 Colt SAA, 1910 Winchester 1892, and 1915 Colt New Service. Brass is available from Starline, and while it doesn't look period correct, the Lee TL401-175-SWC is producing fine accuracy with Unique powder in all three firearms. Here it is compared for size with the .357 magnum.
