If you want to share a camp with your pals, no problem. I have no issue with that at all. But when you fill your tag you should stop carrying a rifle. Every hunter fills his own tag and nobody else's, that's what I mean by no party hunting.
For moose hunting, when you could have up to 15 hunters out to fill a single tag, the odds are much higher that that tag will be filled than if you had one hunter trying to fill one tag. If you lower the success rate, it makes it possible to issue more tags.
For deer hunting, the possibility of one hunter shooting multiple deer and filling everybody else's tags never seemed right to me. Every camp seems to have a few guys that never fill a tag or even see a deer; if you want to carry on hunting go sit with them and give them some pointers.
