The 25 SAW is our short action, non-magnum rifle cartridge based on our 7mm SAW case geometry but necked down to use .257 caliber bullets. It has a maximum cartridge overall length (COAL) of 2.960”, and an H2O case capacity of 54.2gr to overflow. That’s about 5% more case volume than the 25 Creedmoor. What does that mean for real world performance? The biggest advantage comes from the ability to use a wider band of available powders. The SAW case will produce a velocity increase over the Creedmoor of around 50-75FPS, and it allows slower burning/higher load density powders to be used without running out of room. For competition use where a minimum velocity must be met, this means that the 25 SAW can hit required velocities while running at lower chamber pressures, thus increasing usable barrel life. For dual use rifles that may used in both competition and hunting, this means that minimum velocities can be met with shorter barrel lengths, increasing the versatility of the rifle especially when shooting suppressed.
