Great. The OP asks a question, and keeps repeating over and over that he doesn't care about variables like shooter ability, wind and all the other little details that make all the difference in the real world. Silly question, IMHO, but...
So the answer is...eventually...pulled off a chart or out of some ballistic program. It's some ridiculous asinine distance at which almost nobody should actually be shooting at a moose...and at which absolutely nobody needs to shoot at a moose. Attempts to stress the importance of all the other facets of shooting at distance are pretty much ridiculed...this question needs an answer, dammit! Don't confuse us with facts!
Then the next guy reads it, and "realizes" that the .30-06 he just bought...his first centerfire rifle, which he has yet to actually load and fire...is perfectly capable of slaying a moose in the next province over...so therefore he can do so, and fully intends to try.
Of course, the next guy decides to check the charts, because he absolutely needs to know if he can use his .308 instead...or his .260...or his .243...or his .22Hornet...or...or...or whatever, he is pretty sure it'll work, so he's gonna try that out.
Jeez, I hate threads like this...
