Scope Slope
Slope, lookdown, whatever you want to call it, in a perfect world the bore of our rifle and center axis of our scope should not be parallel. They should, instead, converge a certain distance downrange. For shorter ranges and flatter shooting cartridges, slope can usually be ignored. But when we shoot slower cartridges or longer ranges we may have to pay attention to scope slope.
Our goal is to keep our scope in the middle of it's elevation adjustments. If there is a 40 click difference between our chicken and ram settings, we want the scope 20 clicks above the middle of the adjustment range when we are on rams, and 20 clicks below when we are on chickens. The question becomes how much slope is required to get our scope positioned so it is working in it's most efficient range; the middle. We will attempt to answer that question here today.
