How To Measure the Apparent Magnification of a Scope

How would you go about testing if a scope really did provide 25x magnification, or finding the exact point where 18x was on a variable powered scope? That turns out to be a much harder problem to solve that it might seem. In an Outdoor Life article, they said “It turns out to be tricky to measure apparent magnification of an optic, for reasons too mathematical and abstract to mention here.” I concur. In fact, I spent more time talking with optics engineers and industry experts about this question than any other topic. The vision engineers at Edmund Optics offered ...

Shooting Rest: HOG Saddle & PIG Saddle Review

The HOG Saddle represents a new kind of shooting rest that has entered the market, made for extreme precision. It was designed by Josh Stabler, a Marine Scout Sniper and Operation Iraqi Freedom Veteran, who knows a thing or two about demanding field conditions and surgically precise shooting. When Josh was a scout sniper in Iraq, they came up with all kinds of homemade rifle rests to help them get a steady shot when the location didn’t allow them to layout prone (like the one shown below). In fact, Josh said in his experience the majority of shots can’t be ...

CAST YOUR VOTE: What is the best tactical scope?

Update: The field test is now complete, and all the results are published. Click here to view the overall results and ratings for each scope! In a few weeks, I’m starting a large field test for popular tactical scopes in the $1,500+ price range (plan to test $500-1,500 scopes later this year). Like my rangefinder field test, I plan to have a very objective, data-driven approach using a series of empirical tests that focus on: Optical Quality (resolution/clarity, contrast, brightness, etc) Mechanical Precision & Repeatability (tracking, return to zero, internal adjustments, etc) But before I start testing, I thought it’d be fun to ...
