I find 5x to be about the limit if the animal is too close or moving too quickly. I've honestly never tried 6 exactly but I have had my scope on 7 when I needed to make a quick shot and it's much worse than 5. 6 might be OK but I don't want to buy a scope on "might".
4 is definitely OK and 16 is sufficient for woodchucks even to 400, probably 500, yards and certainly deer at any reasonable distance.
Honestly, I'd prefer like 2.5-30 or something but the budget dictates.
In any case, tell me what you think I'm missing. I don't have to buy it.
