Here’s a video from Travis Haley (hat tip, Herschel Smith). In this video, Haley applies the basic steady hold factors (the Army teaches 8, which are a little different from Haley’s) and some excellent TTPs on holding the carbine and zeroing the firearm with both iron and optical sights. (Irons first).
Here’s the next chapter of his video, where he talks about longer range zeroes. The 25/250 meter battlesight zero is falling into eclipse among gunfighters, and 200 and even 300 m zeroes are becoming more common. Haley’s preference is (given his background, not surprising) a 36m battlesight zero confirmed at 300, as is preferred in the USMC. The 25/250 and 36/300 zeroes depend on the fact that the bullet at the shorter distance is passing through the line of sight, rising relative to the LOS, and at the longer distance passing through the LOS, descending relative to it.
Here’s the Army issue “8 Steady Hold Factors” from the M16A1 era, circa 1970. Our comments in Italic type.
- LEFT ARM AND HAND: Rest rifle in “V” formed by thumb and fore- finger. Relax grip, left elbow directly under the rifle. Nowadays, we can shoot lefthanded, so today we talk about “weak” and “strong” hand, not left and right. Travis shows a more modern method of using the weak hand with the thumb over. Also, nowadays, your weak hand pulls the rifle back into the shoulder pocket to avoid putting wayward stresses on your trigger finger.
- BUTT OF STOCK IN POCKET OF SHOULDER: Place the butt of stock firmly into the pocket of the shoulder.
- GRIP OF THE RIGHT HAND:. Grip weapon firmly but not rigidly. Exert a firm rearward pressure to keep butt of stock in proper position. Clenching the strong hand hard is not necessary, because the weak hand now provides the rearward pressure.
- RIGHT ELBOW: The exact position of the right elbow varies from position to position. The right elbow is important to the maintenance of a good pocket for butt of stock.
- STOCK WELD: To obtain stock weld, lower head so that cheek contacts the same place on the stock each time you fire. If you have to “lower” your head to get a good cheek weld, your sight is mounted too low; the more common problem with AR platform rifles is that the sight is too high and it’s hard to get a consistent cheek weld. Hence all the aftermarket stocks and cheekpieces, etc. But the Steady Hold Factor’s point is solid: your connection of face to rifle stock needs to be solid, and most of all consistent: same cheek weld, exactly, every time.
- BREATHING: Take a normal breath, let part of it out, then hold remainder by locking throat. DO NOT ATTEMPT TO HOLD BREATH FOR MORE THAN TEN SECONDS. It seems to help beginners to tell them, take a breath and let it half way out.
- RELAXATION: Learn to relax as much as possible in any firing position. If a firer finds that he cannot relax, the whole position should be adjusted. “Relax” isn’t really the way we’d put it. You want to be loose and not tense, but not sloppy or slow. Too much tension does make your body (and rifle) shake. A sure sign of a novice is a tightly clenched jaw or grinding teeth!
- TRIGGER CONTROL: Press the trigger straight to the rear with a uniform motion so that the sights are not disarranged. The trigger finger should be placed on the trigger so that there is no contact between the finger and the side of the pistol grip. Smoothness on the trigger press is devoutly to be wished. Ideally, you want to tighten the trigger when the sights are on target, stop pressing and hold if they move, and tighten again. If the firing of the weapon surprises you, that’s okay, and a lot better than a jerked trigger.
Some points on zeroes:
- You absolutely must be able to fire the rifle consistently to zero it. Lots of trouble is caused by “social promotion” of guys that haven’t zeroed from the zero range to the rifle qualification range. Resist that promotion; master the tight group first, and the rest all falls into line.
- The Army love to have you take your previous zero off and start with a “mechanical zero.” This is stupid; don’t do it. Mechanical zero, which centers the sights, is like boresighting an optic; you use it when your old zero is lost or the specific serial number gun is new to you.
- If you confirm a zero, you’re done zeroing.
- The Army zeroes with a three round group. This is… you guessed it… stupid. Five rounds, please.
- Most Army units have “that guy” who can’t zero, or several of ’em, and often the problem is “those guys” who are coaching “that guy” can’t teach, can’t coach, and usually can’t shoot either.
- Shooting is not rocket surgery. Get good instruction and follow it and you will get better. Most people who suck at shooting assume they know it all. In the Army, it’s a truism that women learn to shoot better in basic than men do. Why? Our guess is that they don’t come all bound up with a male ego that already “knows it all” with respect to shooting.
- We have learned something from every instructor who’s ever taught us.
