I used to regularly shoot gophers at 250 - 300 yards with my 30-06 by hitting low - the shrapnel/dirt blast would disembowel the vermin and it would pop 3' straight up.
Now that I've got three BR 50 BMG's with NF BR optics, is there any ethical rules? Using a 750 gr A-MAX I can probably hit 1 foot low and kill one. Does that still count? I'm going for 1,500 yards so I can declare anyone with a confirmed kill less than 1,500 inexperienced ( I'm joking - unlike others who've made the same statement /ubbthreads/images/graemlins/smile.gif)
I've got dozens of 100+ yard kills with a .22 rim-fire and no rangefinder.
