I know some guys who shoot the 375 Ackley. They tell me that they can also shoot 375 H&H out of guns chambered for this round. What kind of ballistics does the Ackley have, on average, out of your "standard" 24" bbl with a 300 grain bullet? Is the 375 Ackley the same thing as the 375 Improved? Also, what is the story with the 375 JRS? Is this another wildcat that allows you to fire the standard H&H out of it? What are the "standard" ballistics on it, assuming a 24" bbl and 300 gr bullet?
