I was doing a little testing of scopes recently and devised a sheet as a rough test of resolving power.
Now, wouldn't it be nice if we could build a list of scopes on here for comparison purposes - all using the same test sheet and performing the test in the same way....
Here's what I propose.
- Print off the following sheet
- In a darkened room / hallway, set the target up at 15 yards and illuminate it with a plain 40 watt pearl bulb placed 3 feet in front and 6" to the side of the target.
- Shield the scope from direct light from the bulb then adjust your scope and record the maximum "LPI" for each of the following magnifications. The max "LPI" being where you can still identify individual lines.
- The lowest scope magnification
- The highest scope magnification
- The scope set at 6x mag (if available)
- The scope set at 10x mag (if available)
- Now remove the light shield to allow some light directly into the lens then perform exactly the same test again i.e. record the maximum "LPI" for each of the following magnifications. The max "LPI" being where you can still identify individual lines.
- The lowest scope magnification
- The highest scope magnification
- The scope set at 6x mag (if available)
- The scope set at 10x mag (if available)
I'll post up the results for my scopes and make a table in the articles area if enough others take the challenge
