I agree. You didn't hit the antler. Play it at 25% speed. You can clearly see you bullets path. You may have grazed its neck but you definitely hit a branch on its antler. You can see if fall off after getting hit.
Your second shot hit high, ahead of the shoulder, and hit the neck, probably breaking the spine.
I never had an issue with you. I don't know anything about you. But if your intent is to somehow suggest you are shooting accurately, or hunting ethically, this probably isn't the video to use to suggest it. Frankly, it looks like you're just lobbing shots and hoping for the best.
