PSEsniper, it will depend on the particular bow. My P38 dual cam would shoot a 375 gr arrow around 275 at 55#. Not many other bows will match that. It'll also depend on the single cam bow being compared. All things being equal, the dual cam will be faster. How much is hard to say. Other things make a dual cam a choice to be seriously considered.
