If one's only thought in making a new product is to make money, they will quickly be relegated to the dustbin of history.I have the cmmg kit.
I plan to use it in my first AR with the echo sport.
Come on, you don't think companies make new cartridges just to make more money?
That's a little naive
To make money, one must describe a market opening, and seek to fill it. For example: a higher energy cartridge than 223REM that still fits in GI mags. Or, a SAAMI-spec cartridge that is effectively 300 Whisper, but not a wildcat/proprietary.
So yes, every cartridge has a purpose, however tenuous, that distinguishes it from the others.
