Factors to consider when buying the Best Scope for 400 Yards

Magnification

A scope with at least 9x to 16x magnification is what you’ll need at 400 yards. If you use too little, you may have trouble locating your target; if you use too much, you may lose field of view. For more versatility, look for variable zoom scopes such as 3-12x or 4-16x.

Objective Lens Size

When hunting in the early morning or late at night, a larger objective lens (such as 40mm to 50mm) lets in more light, giving you a brighter, clearer image. But keep in mind that larger lenses may add weight.

Reticle Type

You can compensate for wind drift and bullet drop at 400 yards with a MOA, Mil-Dot, or BDC (Bullet Drop Compensation) reticle. Holdover points provided by these reticles can improve the accuracy of longer shots.

Glass Quality

Superior multi-coated lenses improve clarity and lessen glare. For identifying targets at a distance, brands that use ED (Extra-low Dispersion) glass or fully multi-coated optics offer superior image sharpness and color fidelity.

Durability

If you plan to use your scope in harsh outdoor conditions, it is especially important that it be fogproof, waterproof, and shockproof. High-quality optics typically use sealed, nitrogen- or argon-purged designs and aircraft-grade aluminum.

Best Scope for 400 Yards FAQs

What magnification is ideal for shooting at 400 yards?

A scope with at least 9x to 16x magnification is advised for 400 yards. You can zoom in on far-off targets with a variable scope, such as 4-16x, while still being able to use it at closer ranges.

Can I use a 3-9x scope for 400-yard shots?

Yes, but with limitations. A 3-9x scope can work at 400 yards, especially for larger targets like deer, but it may lack the precision needed for smaller targets or long-range accuracy. If you want more confidence in your shots, consider a higher-powered optic.

Do I need a BDC or Mil-Dot reticle for 400 yards?

Not completely, but they are very beneficial. Holdovers are made easier with a BDC (Bullet Drop Compensation) or Mil-Dot reticle, which also lets you compensate for wind drift and bullet drop, which become more important at 400 yards.

What kind of glass should I look for in a 400-yard scope?

Better light transmission, clarity, and color accuracy are offered by scopes with ED (Extra-low Dispersion) glass or fully multi-coated lenses. This makes it easier to see and recognize your target, even in dimly lit areas.

What’s a good budget range for a quality 400-yard scope?

Reliable scopes range in price from $200 to $600, with some high-end models costing more. The secret is to stay within your budget while balancing durability, glass quality, reticle, and magnification.

Conclusion

As long as you understand which features are most important, selecting the best scope for 400 yards doesn’t have to be difficult. The best scope can significantly impact your long-range accuracy and confidence, from the appropriate magnification and reticle style to glass clarity and turret precision.

Investing in high-quality optics will help you make every shot matter, whether you’re ringing steel at the range or aiming for a trophy buck. You’re one step closer to improving your shooting skills now that you know what to look for. Choose the scope that best fits your shooting style, and make your next 400-yard shot your best to date.
