I am curious to know if the action of a firearm design affects the velocity of the round. For instance, some 45 Automatic handguns are locked (like a 1911 lug type) and some are blow-back breech like the Hi Point design. Does the different design affect the final velocity of the bullet exiting the barrel if all other variables are similar like barrel length, and bore diameter. And, what might that difference be?
I assume in rifles between a bolt action and a semi-auto gas system, that the gas system similar to an AR-15 does negatively affect bullet speed as the gas required to operate the action has to cause some loss relating to bullet velocity. Any knowledge of how much?
This is just a matter of curiosity and does not affect my choice for various weapons.
