I go over some alternative sight-in and rifle zeroing methods that will help you hit your mark.<\/strong><\/h2>\n

There are numerous ways to zero a hunting rifle. I\u2019m not talking about the mechanical process of adjusting the riflescope\u2019s reticle, so it coincides with your bullet\u2019s point of impact. I\u2019m talking about the distances where you make this happen. For years, the standard has been the 100-yard zero, but is it the best? And is it the best for your rifle\/cartridge combination? Here are some things to consider when zeroing your rifle, and you might be surprised to learn the best approach is one that will work with any rifle and cartridge.<\/p>\n

25-Yard Zero<\/strong><\/h2>\n

Many public rifle ranges have target stands positioned in increments of 25 yards, and often when a riflescope is mounted to a rifle\u2014even when bore sighted by some \u201cexpert\u201d at the gun store\u2014you\u2019ll still not be able to hit the target at 100 yards. Placing a target at 25 yards lets you put your first shots on paper. The key is knowing how to make the adjustments necessary, so you\u2019ll also be on paper at 100 yards. For example, your reticle adjustments at 25 yards are one-fourth of what they are at 100 yards, so it will take four times as many clicks at the closer distance.<\/p>\n

Some experts used to suggest a dead-on zero at 25 yards would give you what has often been called a \u201cmaximum point-blank range zero.\u201d The idea was that with such a zero you could hold dead on out to a certain distance and still make a good hit on a big game animal. They were on to something, but their solution\u2014the 25-yard zero\u2014was only close enough for hand grenades not rifles. A 25-yard zero can provide this type of usable trajectory with some cartridges but not many.<\/p>\n

Let\u2019s use a common, 130-grain .270 Winchester load as an example. If you zero at 25 yards your bullet will strike the 100-yard target almost 4 inches above your point of aim, and at 200 yards it will be almost 5 inches high. That\u2019s a bit excessive to make a good kill zone shot. This is one reason the 100-yard zero is more popular, and with our .270 Winchester zeroed at 100 yards, the bullet would strike a 25-yard target about an inch low.<\/p>\n

\"Alternative
Zeroing your rifle is only the beginning. Your mind needs to be zeroed too, so that you know what positions to shoot from what distances.<\/figcaption><\/figure>\n

100-Yard Zero<\/strong><\/h2>\n

The 100-yard zero has been the standard for a long time because with most cartridges, and for most hunters, it works well out to the distance most shots were taken. But with modern high-velocity cartridges, the 100-yard zero does not let you utilize the flat trajectories these cartridges offer. For example: If you zero a common 130-grain .270 Winchester load at 100 yards, the bullet will strike about 6 inches low at 250 yards and around 10 inches low at 300. This means that for any shot beyond about 225 yards you\u2019re going to have to make a correction to get a good hit.<\/p>\n

Because so many hunters are now trying to operate with a sniper-like mindset by dialing in an elevation correction for longer shots, the 100-yard zero makes sense. They just get their DOPE (data of previous engagement) for distances beyond 100 yards and then dial accordingly. This is a very precise way to shoot that works great on the range, but sometimes in the field it takes too much time. It also opens a window for failure because the good hit is dependent on you dialing in the precise\u2014correct\u2014correction. I\u2019ve seen hunters miss shots because they\u2019d previously dialed in a correction and forget to reset for the current shot.<\/p>\n

\"Alternative\"Alternative
If you\u2019re going to dial for every distance, you need data. For big game hunting, you can eliminate dialing out to the distance your bullet can travel in one-third of a second.<\/figcaption><\/figure>\n

200-Yard Zero<\/strong><\/h2>\n

More recently, it has become popular to zero at 200 yards to maximize reach without dialing in a shooting solution or holding high. If we look again at the .270 Winchester, we can see that a 200-yard zero with a common 130-grain bullet will cause the bullet to strike 1\u00bc inches high at 100 yards and about 2\u00bd inches low at 250 yards. But it will still be 6 inches low at 300. This is better than a 100-yard zero, but it still leaves some of the .270 Winchester\u2019s flat trajectory on the table.<\/p>\n

\"Alternative\"Alternative<\/figure>\n

A kill zone on a big game animal is generally considered to be an 8-inch circle. Ideally, you want to zero your rifle so you can hold dead on out to the furthest distance possible and still hit that 8-inch kill zone. But, for practical application a 6-inch circle\u2014kill zone\u2014makes more sense because that gives you a little room for error. Fortunately, there is a way to obtain that zero that will work for any rifle\/cartridge combination.<\/p>\n

1\/3-Second Zero<\/strong><\/h2>\n

The one-third-second zero is similar to the 25-yard zero because with most modern high-velocity cartridges the first distance your bullet will cross your line of sight is near<\/em> 25 yards. But it\u2019s better than the 100- or 200-yard zero, because it allows you to take advantage of everything your cartridge has to offer. The method is based on the distance your bullet travels in one-third of a second, and it works because of the consistency of gravity, which makes all bullets drop at the same rate. Rifle trajectories vary because some bullets travel faster than others and go further in one-third of a second.<\/p>\n

\"Alternative\"Alternative
If tall grass or terrain dictate shooting from the kneeling position, how close do you need to be to get your hit? A good way to find out is to work with the one-third-second zero practice regime.<\/figcaption><\/figure>\n

First, you need to chronograph your rifle to establish the average muzzle velocity of the load you\u2019re using. Next, input that velocity, the bullet\u2019s ballistic coefficient (BC), and the height the center of the riflescope is above the rifle\u2019s bore, into a ballistic program. Then, look to see how far that bullet will travel in one-third of a second. With our .270 Winchester load, the bullet will go 299 yards in one-third of a second. Finally, just sight your rifle in so the bullet strikes 3 inches below your point of aim at that one-third-second distance.<\/p>\n
