[QUOTE="J E Custom, post: 1821504, member: 2736"] Sorry, it wouldn't. Without a bullet you would get very little pressure, but the thrust on the bolt would be different if you shot another cartridge with a smaller or larger case head with no bullet, except it would not have enough thrust to damage/set the lug back. Try this, If you had a piston that had 1 square inch of surface and you applied 1 PSI pressure, you would get 1 pound of force. If you increased the piston to 1 &1/2 square Inches and you applied 1 PSI to the larger piston it would produce 1 & 1/2 pounds of force on the piston. (PSI). J E CUSTOM [/QUOTE]
