Would someone armed with a firearm, typical of the time the second amendment was passed, be able to conduct massacres of the type we experience in our country today?

For example, did the rounds per second able to be produced by those firearms allow someone to take large numbers of lives in mere minutes, or did a slower firing rate allow victims to flee? Did a shooter bent on maximum casualties have to reload after each shot, and if so, might that not have given his intended victims the opportunity to tackle him or her, if not flee?
