The cartridge was initially offered in the Icon series of bolt-action rifles in 2007, which were released at the same time. While ballistic performance was as expected, consumer acceptance was low and the round has not achieved commercial success. The 6.5mm Creedmoor cartridge was created by necking down the .30 Thompson Center, and has achieved widespread popularity.
