Sig Sauer is now officially an optic manufacturer in the industry, while they're already one of the industry's leading beast making world-class firearms, they're new to the optic world.

They didn't just make regular scopes like other companies, what they did is they have leveled up to the competition in long-range shooting by introducing the Ballistic Data Xchange ( BDX ) series electro riflescopes with a digital focal point that can be paired to your smartphone and Sig Sauer rangefinder, which lets the scope calculate holdover automatically without the user doing math.

For hunters, the BDX also shows the distance and kinetic energy transfer indicator that tells the hunter if it's a clean ethical shot, which is called the KinETIC built into every SIERRA3BDX series products.

Pros

  • BDX rangefinder assist with auto holdover calculation, so the shooter can just range the target, point, and shoot
  • Magnification dial automatically adjust holdover point accordingly with a digital focal point
  • KinETHIC provides assistance in assuring ethical hunt by indicating when energy on target drops below a threshold
  • Store ballistic data into your Smartphone and transfer it to the scope
  • Great for new shooters

Cons

  • You might quit learning how to shoot and range the old school

Most Important Features In a Rifle Scope

If you're new to a rifle scope, please check out our full guide on riflescopes here.

Picking a riflescope for 1000 yards hits isn't hard, you just need to understand why each scope is built slightly differently than the others, and know what you need.

The more expensive scope doesn't mean it is the best, it just means you're paying for the brand and special features that don't contribute to the shooting performance

For example, I want something from a reputable manufacturer that is lightweight, great reticle, and most importantly the eye box size.

In order to handle these hard-hitting calibers like the 308 and 300 WIN MAG, the most important thing is the scope must retain zero under heavy recoil.

Objective Lens Size

The first thing you want to look at is the objective lens dimension and glass quality.

The larger the diameter, the more light it gathers than a smaller one.

This will prevent that cloudy look from your a scope on a sunny day because of some scopes will have that problem. Larger objective diameter lens also makes what you see through the scope brighter under low light condition.

Also, remember to pay attention to the glass quality inside the objective lens.

An objective lens of 50mm and above is our go-to choices.

Fast Focus Eyepiece - Never Have Scope Shadow Bother You Again

Scope Shadow

Pay attention here!

Please get a rifle scope with a very big eye box with a fast-focus eyepiece, which means less scope shadow and more room for your eye to move around and STILL have a clear sight picture.

Eye Box is the dimension between the size of the exit pupil and the eye relief distance.

A fast-focus eyepiece lets you perfectly align with the scope without getting rid of scope parallax. A rifle scope with a very narrow eye box sometimes is very difficult to shoot because you have to put extra effort to realign your eye behind the scope perfectly.

A slight movement to the left or right, or up and down can skew your aim and point of impact several inches off at long distances.

What Is The Perfect Eye Box Specification?

Look for a scope with a large exit pupil dimension and long eye relief distance.

The perfect combination is:

  • Large ocular lens (45mm or more, aka large Objective Lens)
  • Long eye relief distance (3.5-4" changes relative to magnification settings)
  • Large exit pupil (8mm or more)

What you will get is a large field of view right in front of your eye without the feel of looking through a small tube.

Most modern scopes feature fast focus, and they're easy to use.

It's an eyepiece that can be adjusted near the ocular lens, kinda like the ones on a binocular. A locking focus scope is a thing of the past, which basically fixed in place, and can't be adjusted until the locking ring is released.

Long Range Calibers

308 still remains as the most popular and readily available round on the market, while new calibers such as the 6.5 Creedmoor and .338 Lapua have a sharper bullet profile than the 308, and they have higher ballistic coefficient without sacrificing case capacity.

They shoot about 200 ft/s faster and further than the 308, with a flatter trajectory overall around 400 - 500 yards, where the 308 has about an 8" MORE drop past 300 yards.

This is where you need to pay attention to how you pick your scope's BDC reticle and ask yourself is it enough for what I needed to do?

While all the above-recommended scopes are high-quality optics that can handle the kick of a 300 Win Mag without losing zero, they work well with all calibers, but the biggest mistake you can make pairs the wrong scope to the wrong caliber without knowing the purpose behind it.

This is where magnification and reticle choices are super important if you want to shoot far with a specific caliber.

What's The Best Magnification For Long Range Shooting

When picking a scope based on the magnification, first you have to understand how far your caliber can reach. Whether that's a 308, 270 Win, 6.5 Creedmoor, 408 Chey-Tac, or 338 Lapua, figure out a realistic distance you want to see clearly through your scope.

Being about to see your 500 - 1000 yard target clearly with your magnified rifle scope is just as important as other aspects of your rifle system.

Sometimes you will lose some field of view due to eye relief, but with a good magnification level can make up for it.

Remember- the greater the magnification, the lesser the eye relief.

Earlier we talked about picking a scope with a good eye box, and the magnification settings relatively change the eye relief distance.

Usually past 6X even with a large exit pupil or ocular lens diameter, the eye box will shrink.

Which Rifle Scope Do I Need for 300 Yards at Minimum?

If eye box and eye relief aren't a major decision point for you, then all you need to focus on is picking the right magnification level.

Pick the best magnification for what you intended to do as far as distance.

So how much magnification do you really need?

For 300 - 500 yards in general, a 4X to 6X magnification will give you enough zoomed image for target shooting and hunting smaller animals.

Magnification Rule of Thumb

For every 100 yards, an additional 1X magnification is recommended.

Anything past 600 yards or 1000 yards, go with a 10X to 15X scope.

Also, remember...

Too much magnification isn't a good thing either because of loss of situational awareness and field of view.

MOA OR MRAD Reticles

MOA VS MIL

Pick the MRAD reticle, and that's what the professionals use.

If you naturally think and talks in centimeters and meters, then it's faster and easier with an MRAD scope and vice versa.

Since the military standardized MRAD scope, it's common to see popularity rise among civilians, and that's just a common trend.

It doesn't mean the MRAD is superior, it just means what works best for you.

Stay with one unit of measurement and don't mix English units and Metrics together.

Picking the correct reticle for long-range shooting is extremely important. Unlike in 3 gun competition where you need a simple uncluttered reticle to shoot fast; in long-range shooting, you need a reticle that helps you predict the POI (Point Of Impact) and bullet trajectory.

In the long-range shooting game, the option to choose between MOA or MRAD reticles significant change how you think and measure targets at distance.

  • MOA stands for Minute Of Angle, and it's usually 1" at 100 yards. Learn more about MOA adjustment Click here.
  • MRAD refers to milliradian which is 3.6" at 100 yards, and the adjustment is usually 0.36" for every click.

1/4 MOA click adjustment is finer than 1/10 MRAD adjustment, but the difference is very small.

Remember!  BDC (Bullet Drop Compensator) reticle is what you should be looking for, and there are so many options out there, and here are some tips.

The bullet drop markings on the reticle are NEVER dead-on accurate, in addition to shooting custom loads through various calibers, the result will vary a lot.

When you shooting up to 200 yards, you can just reference the center crosshair. While you extend beyond 400 yards is when you start to appreciate the BDC holdover reticle markings.
