Backthrust on actions
      18/09/05 06:06 PM

Backthrust

Backthrust = Torque

Upon firing a cartridge backthrust acts to open the locked DR mechanism.

T = Force x Radius

Pressure = Force/Area

Assume the pressure of the cartridge expanding the case head against the face of the action translates the force acting to generate the torque.

Assume the same action ie. identical radius through which the force acts to generate torque.

Then the Torque generated by a 30-06 SAAMI 50,000CUP (head diameter 0.470") would be equivalent to a 45-70 (head size 0.505") at 43,309CUP or a 9.3x74R (head size 0.469") at 50,213CUP.

Am I on the right track?
