I was thinking recently about what makes a successful cartridge and how many Remington and Winchester had to their company. My definition of success would mean there are still new rifles available for purchase for this chambering and you can still buy factory ammo for it from more than one company.

Here is my list:

Remington
223 Remington
22-250 Remington
357 Remington Magnum
44 Remington Magnum
7mm Remington Magnum

Winchester
22 WMR
22 Hornet
243 Winchester
270 Winchester
30-30 Winchester
308 Winchester
300 Winchester Magnum
350 Legend


What others have I forgotten or would you add to the list?
