"When isn't it hunting anymore?"
When the person behind the trigger looses the passion for being in the field. As far as long range hunting goes, a good friend of mine kind of coined a phrase that sums it up, Those that can DO, those that can't BITCH!!!!
I would never tell anyone that their method of hunting is anything but hunting, AS long as they are efficent at cleanly harvesting the game they are hunting.
Personally, I would bet I pass up on FAR more mature bucks every year then most are able to see. I also know that in many parts of the country and even my state that if there are horns its dead. After putting 6 whitetails on the ground that average over 150" B&C, I often let bigger bucks walk then most would ever consider doing.
Let me be clear about my feelings, KILLING is not hunting, Hunting to me is being in the field, WITH the animals and when done correctly, the game animals and the environment you are putting yourself into has no idea you are there and when done correctly, you can hunt the same area day after day and see game every day.
Long Range Hunting IS the very best way to hunt in this maner and have little to any negative impact on the patterns of big game animals.
When the time comes to punch a tag, that is not the defining time of being a hunter, its the hours, days, weeks and months and even years leading up to that point in time. When the time comes to pull the trigger, that is the END of the hunt, not the hunt itself.
Simply put, do what you want, where you want. A good hunter is able to move into the wild field, unnoticed by most others in that natural element and when the time comes efficently and cleanly harvest the big game animal you decide to take.
This debate comes up all the time, again, I fall back on my friends comments, Those that can do, those that can't BITCH!!!
