You can always make the system that we now have work for you. Get an oncore pistol with a 15 inch or longer8mm barrel. I think Savage has a hand gun that would qualify also. So I believe that there a legal ways of getting most of that long range that you seem to want to have. Me the two places that I hunt the most they are not needed. Spend extra money? Nope

If I want quick second shots I can always go back to my Shotgun with a rifled barrel and Remington copper solid sabots. Right now I am pretty happy with my Knight extreme and my Savage ml11.
