Federal, the people who gave you the 9mm Rimmed, proudly present the new "30 Super Carry" cartridge: https://www.federalpremium.com/30supercarry.html
.312 diameter, 100 grain JHP at an advertised 1250 fps. 12 of them will fit in the space that ten 9mm cartridges can occupy.
Smith and Wesson will host the first guns for it: https://www.thefirearmblog.com/blog/...0-super-carry/
Anybody want to take any bets that it will chamber and fire in the French 1935A? https://en.wikipedia.org/wiki/Pistol...%C3%A8le_1935A
