True or False: Generally, the straight blowback action design is found on firearms that use high-pressure centerfire cartridges.

The statement is false because straight blowback action is typically utilized in firearms that use lower pressure cartridges, such as rimfire or some low-pressure centerfire cartridges. This action relies on the mass of the bolt and the spring tension to keep the action closed until the bullet exits the barrel and the pressure drops to a safe level for extraction.

High-pressure centerfire cartridges generate significant recoil forces, which can lead to excessive wear or failure of a straight blowback system due to the inability to safely manage these pressures. Instead, high-pressure cartridges often require more complex designs, such as locked breech actions, which use mechanisms like recoil or gas operation to delay the opening of the action until it is safe. This ensures that the higher pressure does not cause issue in the operation of the firearm.

Overall, the design of the firearm should align with the pressure characteristics of the cartridge it is intended to use, making the statement false as straight blowback is not compatible with high-pressure centerfire cartridges.
