At what range are you most concerned, and what caliber? Will you be using "reactive" targets that cause a yellow or orange circle to form around the hole made by the bullet?
I ask as the farther the distance + the smaller the hole, and without contrast = you need a better quality scope. You are paying for the quality of the lenses and mechanism which = clearer at longer distances. :wink: So for 50 yards, a an inexpensive scopewould work..., even an inexpensive pair of binoculars....perhaps out to 100 yards, especially if you were using a .54 or with contrast targets. Say in the below $100 price range.
However, if you're going to 100 yards with standard black on white NMLRA or other standard targets, and especially if you are going to give 100+ yards a whack with calibers of .50 or smaller (or if you want a spotter that also works well for modern .22's and such at 100 yards) ..., you may want to spend more money for a better distance scope.
Normally, what I have found is that when you get above the $150 mark, you're talking scopes that are sufficiently clear when focused to distinguish holes from .22 - 6.5mm -.30 caliber out to 300 yards..., give or take the brand, and if you're doing 500 - 1000 yard shooting you'll probably start at $400 and work up toward $1000 or more in a spotting scope for competition.
