The .30 TC is a cartridge developed by Thompson Center Arms. It was released for sale in 2007. It was initially offered in the Icon series of bolt-action rifles, which were released at the same time. It was an attempt by Thompson Center to make a 308 Winchester length round with 30-06 Springfield performance. While it did accomplish this goal, consumer acceptance was low, and the round has remained on the sidelines. The 6.5mm Creedmoor cartridge was created by necking down the .30 TC and that cartridge has achieved widespread popularity.
