The 6.5 Creedmoor is a specialty cartridge for guys looking for more X's
across the course and at 1000.
i.e. pros and top competitors fighting the wind, mirage, and various mental/body
If you are not shooting master scores, you don't need to go there.
It was developed by David Emary and Dennis DeMille.
G. David Tubb shoots the 6XC the last time I looked. This is another
specialty cartridge designed to shoot a 115 grain 6mm VLD type bullet.
He says this is the ideal across-the-course cartridge.
These guys focus on performance. If they can come up with something
that will give them an edge they will do it. G. David Tubb is a NO
compromises type guy. Same with DeMille. Of course, either one
could beat me with a gun chambered for 30-30.
