I wonder what muzzle speed would be reached if the bullet was fired without a barrel... Would be relatively pointless, but all interesting stuff

It may not increase velocity but a big jump does reduce pressure due to it having more momentum when it engages the rifling so you could load hotter (why a weatherby mark V has a massive jump), suppose in a round about way it does increase velocity due being able to take a hotter load.
