Besides the round designed for SA guns, part of the secret of the CM is accurate attractively priced rifles and accurate competitively priced ammo off the shelf
Lots of performance without a lot of effort or cost. Millennial generation "snipers" can look pretty good, first trip from their favorite LGS to the range...
More and more of these new rifles have the tacticool look...
An inherently accurate round doesn't hurt. What's not to like.
The market does drive the product.
