thats probably the most incorrect info i've ever heard. I would argue that if you shot it, regardless of wether you recovered it or not its most likely going to die of its injuries. i bet if you asked a CO none of them would agree with your interpretation. the tag says immediately upon KILLING. not RECOVERING. read the back of your tag and maybe ask a CO. sheesh....
ultimately do what you want but for me if i know i hit it. the tag gets cut.
I have to agree with Running, and ask how much experience you have?
If you have a canceled tag and no animal to show for it, a CO will be VERY suspicious of why that would be, ie, did you shoot a 9 point double brow moose and think it was a tri palm or a ten point until after you cut your tag and then got spooked and walked away from it?
The only way to know for certain that you have killed something is to find it and verify that it is dead, by poking it in the blinker with your muzzle (or however you do it).
And I have asked that exact question of multiple CO’s, and that is exactly how they interpret that. Canceled tag and no animal, you did something wrong and they want to find out what that was. A couple of them have said “But if you didn’t find it, how do you know you even hit it? Or if you know you hit it but can’t find it, how do you know it was a mortal wound?”
Do what you like, but be aware that you are wrong. And to be really blunt, the only reason you would cut your tag instead of just stopping hunting for that species (if you feel you killed it but didn’t find it) is because you can’t trust yourself to not shoot another one when the opportunity arises.
Ethics aren’t the things you do when people are watching, ethics are how you govern yourself when nobody is watching.
