Again, I believe that the so-called "brush buster" is a total myth!
So, I don't think that you can EVER be OVER GUNNED, for power, or range!
Murphy's law comes into play when you think that "I'm not going to get a longer shot, so I NEED a short range gun!"
Sure as you go that route, a long range shot will present itself!

My motto is, " LONG range guns/calibers CAN make a SHORT shot! SHORT range calibers CANNOT make a LONG range shot!"
