I am more than convinced based off your post so far that you couldn't ethically take game at the distance that most can comfortably shoot a 10x, so the question is rather moot. Honestly dude....after all of your post here, go buy a cheaper option here in the PX and just go shoot. Figure out what shooting on 10x is like. Figure out what a 30oz optic feels like. Figure out what features you actually want. After that, sell the budget optic for the price you bought it for, and then go buy the nicer optic with confidence.
To stay on topic, 10x at 1000 isn't impossible with the NF 2.5-10x24. The 42mm model would make life a lot easier.
