With 130 gr or lighter bullets the 260 has a slight edge. Target shooters wanted to shoot LONG 140-150 gr bullets and found that they the long bullets took up too much powder space if seated deep enough to fit standard 260 magazines or chambers reducing usable powder space. Plus the barrels were not twisted right. The solution was custom built 260's with correctly twisted barrels, long throats, and modified magazines. Hand loaded ammo was loaded to much longer OAL than standard. Make those modifications to a 260 and it does everything a 6.5 CM does.

The 6.5 CM just does the same thing with off the shelf rifles and ammo.


Most people don't really want the truth.

They just want constant reassurance that what they believe is the truth.
