How To Zero A Scope For A .308

Knowing how to zero a scope for a .308 is a good skill to have. Especially when you’ve attached your scope of choice to your favorite rifle. Now comes the fun part, zeroing it in. You’ll need to know how to zero in a scope so it’s effective and can reach a certain distance. What better way to get this done by going to the range or your favorite place to target practice? If you want to learn how to zero in a scope for your .308, follow along in this guide. Let’s get started:

Install Your .308 Scope

We’ll include this in here just to give you a reminder to install your scope (assuming you haven’t done so yet). If you haven’t, check to see if your rifle is clear. Once you’re all clear, tack that sucker on. This will take a few minutes of your time and a few good tools. Also, it would never hurt to invest in a good scope mount. Mounts come in one-piece or scope rings. Find the best mount that will work better for you so the scope stays in place and doesn’t wiggle around as much.

Get Paper Targets

Paper targets will be needed for zeroing in your scope. One of the paper targets we recommend should include those grids. This way you’ll know specifically how far off your shots might be while taking test shots. This will make adjustments for windage, elevation, and parallax a lot easier. We’ll talk a little more about these adjustments here shortly. But for now, find the best paper targets you can find that will help you make the specified adjustments you may need.

Start Out At A Shorter Distance

The first thing you’ll need to do is start out at a short distance. Ideally, you should start out at around 25 yards. Then you can start taking your shots. Once you are able to consistently hit shots in and around the bullseye, you should begin by situating your targets at longer distances.

Shoot At 100 + yards

Now comes another fun part: hitting your shots from longer distances. This time, your targets should now be set at 100 yards. Like shooting at 25-yard targets, the goal here is to shoot consistent bullseyes. Once you are able to do that, you can go a bit farther up (200-300 yards might be an ideal max distance for .308 rifles).

Additional Tips To Follow

While zeroing in your scope is important, it’s not as easy as you might think. But there are a few tips that you should take to heart while you’re in the process of zeroing in your scope. They are as follows:

Make Adjustments If Needed

Are your shots a little high? Too far to the right? If they appear off somehow, you’ll need to make the right adjustments. Remember that your windage adjustments will be from left to right while elevation will be adjustments going from up to down. For example, if you’re shots are a little off to the right by a hair, then a quick windage adjustment to the left of will work. Remember, most of the windage and elevation adjustments come in increments of ¼ MOA.

Know Your Application

Knowing how far you need to zero in your scope will depend on your intended application. If you’re a target shooter or a competitive shooter, there’s a good chance that zeroing in your scope at 100 yards will be just enough. If you’re a hunter, you can probably get away with zeroing it in as far as 200 to 300 yards to start out. However, there are some .308s that can go quite far for long-range shooting. In that case, you can be able to zero in as far out as 1000 yards.

Know Your Scope

This ties into our previous tip of know your application. Keep in mind that not all scopes are created equal. This means that not every scope will have the ability to reach farther distances (like 500 yards and beyond). It’s important that you choose a scope and know the maximum distance of how far it can reach. You can still target shoot and hunt no matter what the distance is.

Bring Additional Magazines

This might sound like a ridiculous tip, but hear us out. You’re going to be firing off a lot of shots during your zeroing in session. So it’s important that you bring additional magazines that are fully loaded and ready for action. Of course, there will come a time when a magazine will jam on you. So you better have extras for replacements when disaster somehow strikes.

Always Check Your Shots

While checking them through your scope is one way, you’ll need to be able to walk up to the target itself to closely examine your shots. Of course, you’ll need to do this when you can do so safely. Be sure that your rifle is not in a position where you inadvertently end up in the line of fire.

Make Sure Your Zero Is Perfect

We saved the best tip for last. Your zero has to be dead on perfect. There is no room for error here. If you have one at 100 yards, imagine what it would be like at 1000 yards. It’s a disaster waiting to happen. Especially when you hold something like accuracy to a higher standard. While you’re zeroing in, always double check to see everything is perfect before moving on to zeroing in at farther distances.

Learning how to zero in a scope for a .308 is fun to do. But it can be a challenge if you don’t know what you’re doing. Before you get it ready for prime time, you’ll need to zero it in so it will have the ability to reach out and touch something at the distance you desire. No matter if you’re hunting or target shooting, accurate and precise shooting at any distance is all that matters the most.
