How To Adjust The Parallax Settings On Your Rifle Scope

What the heck is Parallax? I asked the same thing when I first started looking to upgrade from iron sight to a good rifle scope. This guide should give you some insight into getting the best focus out of your Bushnell scope, or any other adjustable parallax scope for that matter.

Have you ever looked through a higher power scope and noticed that if you move your eye off center to the edge of the exit pupil, the reticle seems to move across the target? Well, that shift happens when the parallax setting is not properly adjusted for that distance. Some have mistaken the parallax adjustment as a focus or even a range finder, but it is neither of these. The parallax adjustment, when set properly will insure that the reticle is positioned correctly on the target; as though your crosshairs are a part of the target, unmoving, as if they were painted on, just for you. Of course if your scope is not a “target” or a “varmint hunting” rifle scope, you probably don’t need to be concerned with adjusting the parallax setting. In most hunting scopes the parallax is negligible, in fact I have a good friend that hunts regularly and he didn’t even know what I was talking about when I asked him. I don’t hunt, but I love to spend a Saturday at target practice. So to me, any small increase in accuracy is defiantly welcome.

Most of the higher power scopes, with a power of 12 or more, will have an adjustment ring at the end of the Objective bell (the end closest to the target). Usually the parallax adjustment ring has the suggested settings printed on them, so you can just dial in the range you’re shooting from. The problem is these suggested settings are rarely as accurate as they could be. So why should you go through the trouble of getting yours “just right”? Why not just use the suggested setting? Even if you’re a great shot, you could easily shrink the size of your groups by as much as 30%, just by taking the time to properly set the parallax adjustment on your scope. Many shooters don’t even realize that even with a few adjustments they could greatly affect their shooting performance. Let’s face it, the documentation that came with your scope isn’t a real blessing when it comes to learning how to use it, they just assume you already know.

Now that you have an understanding of what parallax is, it’s time to fine tune your scope for increased accuracy. I’m going to assume you have already zeroed in your scope and that it’s properly sighted in. You will need to set up your rifle so it is securely positioned on a bench. A shooting rest with a vise would be best. Dial in the suggested setting on the parallax adjustment ring for the range that you’re shooting from. Now, look through the scope and shift your eye back and forth, left and right so you can see if the crosshairs seem like they are moving across the target. Experiment with the adjustment ring until you have eliminated the illusion that your crosshairs are moving. When you think you’ve got it perfect, take a little white-out liquid paper and make a mark on the parallax adjustment ring so you’ll know where to adjust it later. Some people paint their mark or score it into the metal, but to start with I prefer something that’s not so permanent until I’m absolutely certain about the position. Next, go ahead and take three to six shots and see how your grouping has improved. Nice, huh! Don’t stop there, move your target 50 yards back and repeat the process. You might as well find the perfect settings for all the ranges that you typically shoot from in 50 yard increments.

If you’re in the market for an affordable rifle scope that will really go the distance I can recommend two models from the Banner series of the Bushnell Scopes line of rifle scopes. The 1st is Bushnell Scopes Banner 6-18×50. This is a long range target scope that is also great for varmint hunting, and it’s parallax focus can be adjusted from 10 meters to infinity. The 2nd is Bushnell Scopes Banner 6-24×40. This long range target and varmint scope features a mil-dot reticle which is my preferred style of crosshair. Both can be purchased for around $120.00, so they won’t empty your wallet. To view these and other Banner series Bushnell scopes please visit my Bushnell Scopes page.

Happy Hunting,

Accu-Ranger Reticle With Redfield Revenge Scopes: Quick Aiming Without Rangefinder

Have you ever been faced with a situation when your target ran away while you were preparing your shot? If so, you will have wondered if there is any way to resolve this issue. Consider that you need to allow a period of time in which to determine the distance to the target if it’s far away, and that then you need to find an appropriate point for holdover or to adjust the elevation knob. After all, you need to find the most comfortable position from which to make a precise shot. You can consider yourself lucky if the game stays in the same position while all this preparation is taking place. But what if it doesn’t? The timing in such a situation is quite critical.

Redfield has solved this problem. The Revenge hunting scopes series features the unique Accu-Ranger reticle. With this reticle you can quickly determine the distance to the target and make your shot without any delay, whilst keeping your eyes on the target at all times. It may sound like some expensive rifle scope with laser rangefinder − but, in fact, it’s not. The range estimation performs by virtue of the scope’s optics and mechanics, and that is what makes this scope affordable. Let’s see how the Accu-Ranger reticle works.

The upper vertical post has hash marks called brackets. Each of these brackets refers to a specific animal. All you need to do is to turn the magnification ring until an animal’s body appears between the bracket and center of the reticle. There is another horizontal line that moves along the upper vertical post while you are changing the magnification. The vertical post has numbers from two to six, which refer to 200, 300, 400, 500 and 600 yards. When you have got your game between the brackets, look at the upper horizontal line. If it has stopped at number four, it means that your game is 400 yards away. Now just use an appropriate aiming point for hold over and make your shot.

As you can see, the system is very simple: bracket the animal and make a shot. The price is really affordable for a scope with range estimation ability and a ballistic reticle.

To ensure that the Accu-Ranger reticle meets the requirements of every hunter, Redfield has designed four different types: Crossbow, Hunter, Sabot ML and Varmint.

All these reticles come with brackets for 16″ and 25″ targets, while the Varmint reticle features an 8″ bracket. The 8″ bracket can be used for prairie dogs or other similar-sized varmints. The 16″ bracket will be correct for a deer, while the 25″ bracket is designed for elks and coyotes.

The Accu-Ranger Crossbow is a unique reticle in this series and was designed especially for crossbow hunters. This reticle estimates the distance up to 60 yards and has holdover points for the same yardage.

The Accu-Ranger Crossbow reticle is designed to be used with different velocities. At higher magnification, this reticle works well with arrows or bolts that have 425 fps velocities, whilst at lower magnification, this reticle is good for use with 250 fps cartridges.

This reticle comes with the Redfield Revenge 2-7x34mm.

The Accu-Ranger Hunter reticle is designed to be used with elks, deer, coyotes or other animals of similar size. This reticle allows you to estimate the distance up to 600 yards, and has holdover points for the same yardage.

The center of the Accu-Ranger Hunter reticle is calibrated for a distance of 200 yards. This reticle is great for velocities of 2900 – 3800 fps, and works with the following cartridges: .338 RUM, .338 Win Mag, .300 WSM, .300 Win Mag, .30-06 Springfield, 7mm Rem Mag, .280 Rem, .270 Win, .270 WSM, .25-06 Rem, .243 Win, .22-250 Rem, and .223 Rem.

The Hunter reticle is the most popular in the Accu-Ranger series and comes with the following scopes:

  • Revenge 3-9×42
  • Revenge 3-9×52
  • Revenge 4-12×42

The Accu-Ranger Sabot ML reticle has the same estimation range as the Hunter reticle (200-600 yards) and is designed for muzzleloaders and shotguns. However, its aiming points for bullet drop compensation are calibrated at distances of 150, 200, 250 and 300. Center crosshair is zeroed at 100 yards.

The Sabot ML reticle can be used with cartridges of most velocities. At high magnification settings this reticle works fine with 45 caliber plastic tipped bullets (250 grain, 2200 fps).

The Accu-Ranger Sabot ML reticle is available in the Redfield Revenge 3-9×42.

The Accu-Ranger Varmint reticle has an 8″ bracket for prairie dogs as well as 16″ and 25″ brackets. This reticle works well with the most flat shooting cartridges with velocities of 3100-4000 fps. The Varmint reticle is universal. You can use it either for varmint or big game hunting.

The Accu-Ranger Varmint reticle allows you to estimate the distance and hold over for the bullet drop at a distance of up to 600 yards. This reticle is designed to be used with the following cartridges: .300 Win Mag., 7mm Rem Mag, .270 Weatherby, .270 WSM, .270 Win, .25-06 Rem, .243 Win, .223 WSSM, .223 Swift, .220 Swift, .22-250 Rem, .222 Rem, .223 Rem, and .17 Rem.

The Varmint reticle comes with the Redfield Revenge 4-12×42 and the Revenge 6-18×40.

The only drawback with the Accu-Ranger reticles is that they are designed to work for particular animals. However, they can also be used for similar-sized objects. If you are hunting prairie dogs, deer, elk or coyotes, you will usually find that Redfield Revenge scopes are just right for you. At a price range of $139.99 – $249.99, these scopes that have range estimation ability and bullet drop compensating reticles are a very good deal indeed.
