Judging by some of the detractors of the CM, let's not forget why and how it was developed. It was supposed to be the next best 1000 yard, paper puncher.
The genesis of it was printed in the Rifleman or Am. Hunter. After in that arena for about 10 years, it transitioned over to hunting.
And the 300 WSM has been a staple of the 1000 yard game.
