I wouldn't argue with most of the definitions stated for LR/ELR, but in practice, when the range exceeds 500 yards, I'm in full long range mode. My rifle, load, conditions, and target/game will define my long range maximum distance for the shot. The difference between LR and ELR seems ambiguous to me. I've shot antelope as far at 1188 yards when all conditions were understood and accounted for. Given this, I personally define ELR as the range beyond my current equipment/skill level, and something to strive towards. This process has been evolving for me over many years, when making a certain shot on an animal at 500 yards was a pipe dream
