What was the First smokeless cartridge?

Answer 1

The 8mm Lebel was introduced in 1886

7.65 x53mm Belgian Mauser (Argentine) adopted 1889

6.5 x 55mm Swede / Norweigen Mauser, 1891

30 US Army (30-40 Krag) 1892

7x57mm Mauser 1892

303 Savage 1894

6mm Lee Navy 1894, ( a rimmed version was tried in 1891.)

303 British converted to Smokeless in the 1890s

6.5x50mm Semi-Rimmed (6.5x50SR) Japan 1897

Winchester started working on the smokeless 30-30 in 1891, this was a spin -off of their work with the Army on the 30 US Army (30-40 Krag) round.

This eventually resulted in the .30 WINCHESTER SMOKELESScartridge which carried the .30 W.C.F. (Winchester Center Fire) designation on the head stamp, first appeared in Winchester's catalog No. 55, dated August, 1895.

Union Metallic Cartridge Company (U.M.C.) was later contracted to make a copy of this cartridge for Marlin. So the name 30-30 was born. This is also how the 38WFC became the 38-40 when chambered in Marlin rifles. ..
