6mm GT (Gay Tiger)
The GT in 6mm GT, stands for George and Tom, the two guys who developed the cartridge, out of the need to have a 6mm cartridge that can use the forgiving propellants that the 6BR, 6BRX, 6BRA and 6mm Dasher use providing large nodes making load development easier for each new barrel, whilst still being able to feed from a magazine reliably like a 6mm Creedmoor. They also wanted it to be more forgiving on the barrel life, and still provide comparable high muzzle velocities with tight twists required to stabilize the long high-BC 6mm bullets.
