How does the quickness of a powder affect the op-rod?
From what I understand the quickenss relates to how fast the powder will develop max pressure compared to some standard powder.
So, when the primer fires, and the powder does its job, why do the 'quicker' powders bend op rods? The Garand needs about 2kpsi (IIRC) at the gas port to function... why do I care if the pressure is generated at the breech (with a fast powder) or near the muzzle (with a slow powder)... 2kpsi is 2kpsi.
What am I missing?
