Here we go again ethical shooting, don't shoot over 200 yards or it will offend everyone, I hope these aren't the same guys who are saying using a 223 or 22-250 is unethical, because at 200 yards or less, it is a dead deer with proper shot placement.
Moose are hard to hit a 500 yards with a 7mm Rem Mag, they have vital zone,, only the size of a small car.
You better practice if you are shooting at these ranges, many don't, thus the backlash when you speak of 500 yards plus.
