I had a similar experience about 12 years ago.
Had a good friend bring along 2 guys unknown to me and their 12 year old son.
My buddy informed me all 3 were excellent marksman and very experienced hunting our small Fallow deer. We were hunting the much larger Sambar which are vastly harder to hunt than Fallow.
The first morning we head out on a 2+ hour trek to the hunting area. We take it very slow and stop to glass every 10 mins or so.
We stop at one gully head and I glass the gullies to our left, just as I'm about to glass the gullies to our right..........BOOM!!!
The kid has spotted a spike deer about a half kilometre away and proceeds to hastily shoot OFFHAND. No ranging, no glassing by his dad or uncle, they just stand there giving the kid encouragement.
Before I could say ANYTHING, the dad brings his rifle up and starts firing, my buddy then starts yelling at them to STOP SHOOTING.
After all the excitement, I simply say that NONE of them knew the range, yet continued spraying bullets without EVER knowing how far short they were falling.
The rest of the day was extremely tense, the kid was ****ed that he didn't get the deer and, the dad was ****ed that he was TOLD by us to stop shooting.
The rest of the trip to the hunting area was devoid of any animals, not a single deer was seen for 3 days after that incident.
The trip was supposed to be 5 days, the other party pulled up stumps and left on the afternoon of the third day.
I have never seen them since and really don't want to.
Since that incident, I had hunted with another guy, but he became one of those "why should you get the next shot" guys. I ended that pretty quick.
My buddy from the first incident and I hunt together 3-4 times a year, but never side by side, he has his patch and I have mine. We help each other packing out animals by way of a radio, but that's it.
I hunt with my dad more than anyone else. He is 73 and still quite fit and agile, we don't walk as far as when I'm solo, but he does his fair share carrying out etc.
I find people's jealousy/envy the real kicker when hunting, they just can't be happy for the other person, this is why I mostly hunt alone these days.
Cheers.
