The theme here is that almost any factory ammo you can find will likely shoot well in your CM. I have yet to load for mine due to the accuracy of Hornady's Precision Hunter ammo and the 143 ELD-X bullet.
Before I got around to handloading 140's and 143's I bought some Win white box 125's that really sucked with groups approaching 1.75". Horrors!
Now I just use them for off-hand practice and collect the brass...
