Is anyone using a fixed 10 power scope on their elk hunting rifles. I am considering putting a Bushnell 3200 elite fixed 10 with target knobs or a supersniper 10 power on my 300 win mag for elk hunting. I don't have the cash to put a dependable variable power scope with target knobs. I live in Idaho and most of the time I am not shooting closer than 150 yards. I am wondering if this will be too magnified or too small a field of view. Thanks for any input.
