I want to put a scope on my remington 597 and was wondering how much magnification I should be looking for. I've seen some good deals on used 3-9x40 and fixed 10x40 bushnell elite scopes around where I live and was wondering which of these two would serve me better on a .22 which I'll be using just for plinking at <100 yards. I've never purchased a scope before and I know very little about optics in general so any help would be great.
