You're correct, long range "hunting" is a very controversial topic. Long range archery where the target is not the worse for wear when the point of impact, is not the intended point, and can't bleed, only one's ego will be damaged.
To compare long range hunting using firearms and archery is flawed logic, IMO.
Betting an animal at 300> yards will not move from the time the trigger is pulled until the bullet arrives is money in the bank. Making the same bet using archery equipment with the game animal at 100 yards, in some cases half that, could result in a unrecoverable wounded animal.
If your willing it live with this risk factor, long range bowhunting may be for you.
I understand positions people take on both sides an that's why I'm not trying to tell anyone what you're doing is wrong, just expressing my opinion.
