I think most rifle shooters know the term “minute of angle” (MOA) refers to a measurement you dial onto your scope, to change the point of impact on target by the same measure.
For example, my target scopes are calibrated so eight “clicks” on the turret, either for windage or elevation, will move the bullet on target by one minute of angle. That's my March scope featured at the top of the post. This is a relatively fine adjustment, used by the benchrest crowd.
In contrast, some scopes will be calibrated four clicks per MOA for hunting, and others one click per MOA for long-range applications.
If you need to dial 24 MOA elevation onto your scope, you won't be using one graduated in 1/8th MOA! But the fine MOA adjustable optic is perfect for short-range benchrest. I zero the rifle to shoot dead-center in a calm condition, and then hold for windage. Once I've adjusted the scope zero for range conditions, I will rarely make any further windage adjustments to the turrets during a competition, no matter how hard the wind blows.
The image above is a Leupold scope reticle dubbed the FireDot Wind-Plex. The reticle aids in compensating for crosswinds. The hash marks are in one MOA increments, and extend to ten MOA on each side. You can read more about this scope, and find other examples of MOA (and Mil-Dot) scopes on Leupold's website.
But just what is a minute of angle, and how is it used to dial, or hold, for the wind?
The 2009 Super Shoot is now history and during this event, history was made. Tony Boyer won the two-gun for an unprecedented fifth time. He and Don Geraci had been tied with four victories each before this year’s event.
The interview was done prior to the beginning of the competition, but I had a feeling that Tony was hungry for the fifth victory.
Faye Boyer is the only female member in the Benchrest Hall of Fame. This attests to her tremendous skill as a Benchrest shooter. She along with Allen Arnette and Wayne Campbell, earned Hall of Fame honors with Tony as a mentor.
Tony told me that he has no secrets, but he sure has methods that seem to improve the ability of those who he teaches.
Hey shooters, today I’m reviewing the rifle scopes I use in short-range competition. Now before my long-range friends unsubscribe, trust me that you’ll find this an interesting blog post—regardless of the brand of scope you own, or your shooting sport!
I’ll share tips on how to prevent damage to your optics, and the pros and cons of different scope magnifications and objectives.
And you’ll see my own equipment, and why I love it.
