Frequently Asked Questions

What to Look For in a .308 Rifle Scope?

Choosing a riflescope for a .308 rifle should be made after considering several factors. 

  • Magnification – The .308 Winchester round can easily go beyond 800 yards.  Your rifle scope should have enough magnification to make seeing your target at that distance easy, even under the most challenging conditions.  Factors such as clarity, optics coatings, and low-light transmission also figure into the choice.
  • Eye Relief – Heavier recoil cartridges like the .308 Winchester require a generous eye relief to protect yourself.  Choosing a riflescope with a longer eye relief can help you avoid some nasty results from getting to close to the end of your scope.
  • Weight – If you are a hunter who may face a long trek through harsh terrain, the added weight of the scope to your rifle can be a concern.  Finding the sweet spot between weight and the ability of the scope to absorb recoil is always a challenge but must be considered.
  • Reticle – The style of the reticle is more a personal choice than an operational option.  If you are more comfortable with a BDC reticle over a mil-dot style scope, you should certainly opt for your comfort.

What Rifle Scope does the U.S. Military Use?

The current issue rifle scope for U.S. army precision shooters is the Leupold Mark 5HD 5-25×56 riflescope.  This scope, according to Leupold, was designed from the ground up to meet the demands of the U.S. Army specifications precisely. 

The Leupold scope features an MRAD reticle and is suitable for the NATO 7.62 x 52 round as well as the .300 Norma Magnum and the .338 Norma Magnum cartridges.

How do I Know What Magnification to Choose?

Selecting the maximum magnification for a .308 Winchester riflescope is a matter of how you use the scope.  In general, these rules apply to choose the magnification for your riflescope.

  • The maximum distance to the target – In general, the further the goal, the higher the magnification you want. 
  • The type of shooting you will do – If you are hunting, you will rarely take a shot more than 300 yards.  Unless your eyesight is poor, a lower magnification scope is probably more than adequate.  On the other hand, if you are a competitive shooter who routinely engages targets beyond 800 yards, more magnification is probably on your list.
  • Zoom or fixed magnification? – Hunting is usually done at relatively unchanging known ranges.  A fixed magnification scope may be a better choice.  Without all the internal moving parts that come with a variable magnification scope, these fixed magnification scopes tend to be more durable.  If you are shooting in conditions where ranges vary considerably, a zoom style scope is probably a better choice.

Down Range is the Ultimate Answer

In the end, the goal is put to rounds on target, consistently and with the minimum of effort.  That should be the overriding factor in choosing the riflescope for you .308 Winchester rifle.  Our choices kept that very thought in mind.  We hope that you find the information we have provided useful.
