Quote: 6.5x68 with 90 gr projectiles reportedly 3900 fps plus. Used for mountain chamois.
So would the .264 Win Mag.
Was thinking the .204 Ruger would hit that mark as well...
"Pushing the 32-grain bullets to a muzzle velocity of 4100 fps and the 40-grain bullets to 3900 fps, the . 204 Ruger is one of our fastest cartridges."
