I'm looking to set up my rifle for coyote hunting, but am worried that a scope may not be very effective on an elevated sight rail. To clarify, I am worried that if i put a scope on it and zeroed it at 100 yards, it would be significantly off at 25 yards due to the slope of the rail. Am I thinking too much into this or am I correct. If so, what measures can I take to compensate for this? Just don't want to drop $200 on a nice scope that I won't be able to use. Thanks in advance.
