I'm going to play devils advocate. I own a Hawkeye borescope and I have no complaints about how well it functions. But how much does inspecting a rifle barrel with a borescope tell you? From my experience Shooting a rife carefully for accuracy is a far better indicator of a good...

It no doubt did shoot sub-moa at 100 yards. That has little to do with how it will shoot at 500 to 1000 yard distances. The typical unaided human eye can resolve about 1 arc minute. At 1000 yards one arc minute is about 10 inches diameter. What do you expect to shoot at 1000 yards...

I also use and like the Horus Falcon. It's concept of use is quite different from other long range scopes in that there is no knob twiddling other then for setting the zero to align the rifle to the scope for the calculations used. The scope can be moved to a different rifle with quick...

So far i haven't found a scope which can measure downrange crosswinds and from that calculate bullet deflection automatically. Until the I'll use my old Leupold Mk 4 16x4 mil dot. After 40 years of shooing I'm starting to learn to dope wind and to know when it's not possible. Compromise...

For a detailed explanation of the correct equation which explains wind deflection and which is used in every ballistics computer program see: Modern Exterior Ballistics by Robert L. McCoy 1999 section 7.4 "The effect of constant crosswind on the flat-fire trajectory" The equation was...

The setup described above knows nothing about downrange crosswinds. That is the largest source of shooting error which cannot be measured and computed with commercially affordable instruments. There is still no practical alternative to learning the shooting skill of visual downrange...

The damage to a scope which is properly mounted in rings will be far less from firing thousands of rounds than from dropping the rifle once scope first a foot onto a rock. You just don't notice the damage until the next time you shoot and it wont hold zero. Round count means...

Spending a lot of money on a fine rifle with excellent ballistics will be a waste beyond about 1500 yards unless you figure out a way to get a handle on downrange crosswinds. You can use spotter rounds if the target area will give visible dust puffs or if you have a downrange spotter...

What do "official" and "group size" have to do with hunting? The measurement techniques described above are right for bench rest and similar competition, but shooting for score on target rings is somewhat more realistic as the measure of a hunting rifle. No form of fixed range...

What's important is that your eye aligns comfortably behind the scope when you have a comfortable hold on the rifle. A proper hold is a subject of it's own. Proper scope height depends not only on the rifle and scope but every bit as much on the shape and dimensions of YOUR face...

It's your face which needs to have a comfortable fit so your eye will be centered on the scope when your cheek is snuggled against your trigger hand and stock. I keep a few cheap import ring sets just for testing rifles for a comfortable fit to scopes being fitted to rifles. After...

The LTI Impulse series was not specifically designed for shooters. I own an Impluse 2000 XL and an Impulse 2K. They have similar range and accuracy but the XL adds an inclinometer, some trig functions, and a serial computer interface. Relative to some other rangefinders, the Impuls...

Do you mean liking the Horus scopes or the Horus mil-grid reticles or the concept of using a mil-grid reticle as an alternative to twiddling target knobs? To use a mil-grid reticle effectively you need a method of converting range measured by some accurate method like a laser rangefinder...

What's the light for?

At least get a proper eye exam. There are two main types of eye doctors. Opthamologists study all forms eye irregularities and are medical doctors. Optometrists are skilled technicians who measure for and fit corrective deices like glasses and contact lenses. There are others who do...
