I shoot inside 50m with my scope set either at 4 or 6 and have no trouble with target acquisition on small wallabies, even as close as 15m. If you're having issues acquiring your deer sized target you are doing something wrong but that's just my opinion. I suggest you get your 22lr and 500 rounds, a bunch of empty cans, set them up at random ranges and at various angles. Practice setting your stance for each target (address target with stance), fix the target in your gaze, raise rifle to shoulder and scope to eye in one motion and pull the trigger. You'll soon get the hang of it.
I agree that higher mag scopes are more difficult at closer ranges but still think the difference between 2x-3x is bugger all if you practice acquiring your target. That's what your 22lr is for, not just randomly shooting as many rounds as you can afford but for practicing specific techniques. Just my OCD coming out and 23 years of king fu.

Plus, a Swarovski is so much sexier than some loopi!
