my load for the 250 RN is 53.5gr of 4064 and my crony only shows it to be about 2244fps on average. its out of a 7600 pump w/ a 18.5" barrel. i know the velocity would be less then a 22" tube but that seems like a turtle to me. i dodnt get to kill anything w/ that load last year so on game performance is still a mystery. if i could get it to 2500fps MV ide be pretty happy w/ it and use that as a do all load for up here killing deer, bear and moose but im wondering if it will expand on somehting like a 150-250lb buck BUT be tough enough for a 950lb moose. what do ya think
