yards = 8/4, and 1,000 yards = 10/4. As these old-timer shooters compute the clicks, though, they say it out loud as, "Why, 400 yards, that's four-quarters of an inch, or one full inch," meaning one click will equal an inch of movement. "And 700 yards, that's seven-quarters of an inch, or one and three-quarters movement per click."

My good friend Jim "K-Bar" Kauber, a retired Navy SEAL Master Chief and former Gunsite precision rifle rangemaster, has his own handy formula for determining sight changes at various distances. Let's say you've fired a shot at 300 yards and your spotter reports it hit 15 inches low. Here's Jim's formula for calculating the correction in Minutes of Angle:

Correction (in inches)

Distance (in hundreds of yards)

= MOA correction

Let's try it with the numbers from our example:

15 (inches)

3 (hundreds of yards)

= 5 MOA correction

The lower line of 1/4 MOA equivalents tells you what one click equals for the indicated ranges. To remember it, just recall that it stares as 1/4 inch at 100 yards—which is identical to the 1/4 MOA increments of your scope—then grows by 1/4 inch each 100 yards. It's an easily understood progression, and if you keep it straight in your mind, you'll avoid a lot of confusion later.

What does one click equal at 300 yards? That's easy—3/4 inches. (You remembered the progression: 1/4, 1/2, then 3/4 for 300 yards.)

A faster way used by long-range target shooters is to fractionalize the 1/4 MOA equivalents, so that 100 yards = 1/4, 200 yards = 2/4, 300 yards = 3/4, 400 yards = 4/4, 800

It doesn't matter so much which way you mentally compute MOAs and clicks, but you must have one way and practice it. After a while, you'll find yourself clicking in changes about as quick as your spotter calls your shot.

The solution to the windage compensation, above, is two clicks right. Recall that at 700 yards 1 MOA equals 7 inches, and each 1/4 MOA click will move the strike of the bullet 1 3/4 inches (seven-quarters, according to an old-timer). Two clicks at 1 3/4 inches cach equals 3 1/2 inches, which is as close as you're going to get.
