The 6mm Remington design is printed in full color (front/back) on a Light Sand or Ash color, 100% Pre-shrunk Cotton Shirt (Gildan 2000).  It includes the cartridge schematics.

The 6mm Remington, originally introduced in 1955 as the .244 Remington, was based on the .257 Roberts case necked down to 6mm. Initially paired with a 1:12 twist barrel for lighter varmint bullets, it struggled against the .243 Winchester. Remington reintroduced it in 1963 with a faster 1:9 twist and new name. Despite excellent ballistics and versatility for varmints, predators and deer, it never regained market dominance but remains a respected, accurate cartridge used by classic collectors.
