It is amazing to look at the chart above and see how quickly the velocity drops off for the prb. At 150 yds almost half of the velocity is lost to wind resistance. Since energy is 1/2 Mass X Velocity Squared, only 1/4 of the energy is left. The conical has not even lost 1/5 of its V at 250 yds And consequently retains much more energy. Assuming that both loads were reasonably accurate, the vote goes to the conical.
