How does more powder, less powder & OAL affect the accuracy of the projectile? Granted, control of shot placement is in the hand of the shooter but how do these other factors affect projectile flight? Does OAL mainly contribute to the function of a SA pistol? Does more / less powder do more than contribute to the recoil amplitude? I am just trying to understand what part do these three factors play in a "perfect world" as if the gun were clamped in a Ransom Rest.
