Personally I like to know where my bullet will be at each distance...
I understand to each their own, but point blank isn't my cup of a tea, I think simply knowing that out to say 300yds you can just point and probably hit the animal is nice case of a quick shot.
but I'd rather be dead on at each distance, instead of high close up, and low down range, if you'll be 3" low at 300yds, hold up 3" and hit dead on.
shoot and check....and also punch in some load info in a ballistics calculator, or just check the charts from the factory for some reference.
