If there’s a favorite rifle cartridge in America, it’s got to be the .308. No other cartridge improved upon the King, the .30-06, and the 5.56 is just too tiny to take the top slot. Among hunters, there’s no comparison the .308 Winchester is by far the most common hunting ground in the United States.

How to Choose a Rifle Scope for a .308?
If you’re looking for a new scope whether it’s for a short-barreled FN scar, an exotic tikka ctr or your standby X-bolt, there’s an excellent new scope out there tailor made for your .308. Here’s a few tips and tricks to choose the best 308 scope for your rifle and a few recommendations if you’ve never bought a scope before.
Size & Weight
Over the years optics have been getting lighter and lighter. At the same time manufacturers are able to come out with optics with larger and larger objective bells. In fact, it’s not uncommon these days to see AR 15’s outfitted with scopes that have 56 mm objective bells. This is not necessarily a bad thing, but the larger and heavier your scope is, the more of a hindrance is going to be.
Determine the relative size the objective bell you need before you go shopping. If you never bought a scope before this can be difficult, all you know is a large objective bell gathers light better than the smaller one, but that the quality of the glass inside the objective bell matters more than the overall size.
The difference in performance that you gain from a 40 mm to 56 mm objective bell is negligible if the lenses inside have subpar coatings. Same goes going for a 1 inch tube to a 30 mm, rarely is it worth the increase in weight and size for the average shooter.
Everybody has a different tolerance with the amount of weight they are willing to carry, but for a .308 rifle anything heavier than 8 pounds isn’t necessary. Unless you are assembling a solely bench rest rifle used for competitions, a lightweight rifles going to be easier to travel with, easier to clean and at the end of the day more enjoyable to shoot. Lightweight and compact rifles are especially important for hunters.
The budget that you set out for your riflescope should be proportional to the rifle that your shooting. Obviously, if you have the new Ruger precision rifle you can afford to spend money on something a little nicer than an inexpensive fixed power scope.
The goal is to use a magnified optic to get the most performance out of your rifle as possible. Depending on the rifle you have, and the job you want to do this can require $300 or $1300. Most scopes these days cause under $500 and even the absolute best in the industry costing under $1000. Many people even be hard-pressed to not be able to find a totally usable scope for $300.
Your budget is going to be extremely personalized but to get the most out of it consider buying for major manufacturers, not boutique brands. You don’t want to go with a cheap fly-by-night import company, but not paying for brand name is a great way to start off ahead.
Many of the major manufacturers but especially Leupold, Bushnell, and Vortex offer exceptional value priced optics all three of which have purpose made .308 Winchester scopes for under $300. These scopes can be used out in excess of 800 yards. It’s all about what you are willing to use and the type of scope you want
The great thing about shooting a .308 is that you can have literally anything you want. From holographic sights made to be as inexpensive as possible but still have BDC reticle, all the way up to extraordinarily specialized tactical, military style scopes designed to be able to hit targets as far away as the moon.
Determine what you’re going to be doing with your rifle before you go shopping. That is the best way to make sure that you stay within your budget, and you buy scope that you will be happy to use a year from now once all of the newness has worn off. The aim is to get a scope that maximizes the usefulness of your rifle.
At a minimum, look for a scope that will shoot the distances that you want to shoot, and a package that you are willing to carry all day long. It is very easy to buy a scope with twice as much magnification as you need, but you’ll instantly regretted the first time you go hunting.
Nail down general criteria of what you want your rifle to do and then have a realistic expectation of the type of scope that you should get. Small features like BDC reticles, second focal plane reticles, rugged exterior coatings, sunshades, and other small refinements can be had for virtually no trade off in cost.
Larger features like target turrets and 30 mm tubes can double or triple the cost of the scope and make it much more difficult carry in the field. Determine whether or not it’s worth it to you.

Features You’ll Want
Depending on the type of rifle you have, and a particular type of job you have in mind for. You’re going to want a number of different features to get the most out of your scope. The market is littered with specialized and proprietary technologies that make scopes more effective in the field and make rifles easier to use. Here’s a list of some of the features that you may want on your scope:
#1. Specialized Coatings
The new frontier of scope customization is proprietary and specialized coatings. What this means, is not refining the typical fully multicoated lens systems that have been on the market for several years. What manufacturers are now incorporating the designs is the filtering the light that allows you to better see your target space in which will be shooting at.
For example, a scope marketed specifically for a deer rifle will have coatings that filter out red wavelengths better so that you can see brown colored animals easier in the brush. For target shooters, this means a filtering of light that better allows you to see shades of black and gray at long ranges in low light.
These specialized coatings are not available from every manufacturer, and only on select models but if you are going to buy a high-end rifle scope made for a specific purpose, this is a feature that you will definitely want to take advantage of. It may seem like a small detail, but it can certainly make a difference at the very edge of shooting light or the competition.
#2. Target Turrets
Target turrets are difficult recommend. Mostly because they have a steep learning curve that many shooters never copper. The use of target turrets and competitions is standard practice but for hunting, are nearly never used. Depending on the type of hunting or shooting that you are going to be doing, the use of target turrets may be extremely important.
Take into account the skill level of the average shooter most people can get by with standard turrets because the associated weight, bulk and cost of adding even standard target turrets to a scope outweighs any benefit they provide.
However, if you are willing to put the time in to properly learn how to use target turrets and are willing to invest the money, especially a custom set up like Leupold can provide, you can have greatly increased precision at long-range.
#3. BDC Reticles
If there’s one feature that you should never pass up on a given the opportunity, it’s a BDC reticle. A BDC reticle is a design that is utilized for the site picture on your scope to allow you to reliably predict the arc of your bullet to know ranges.
While they are never dead on, even when custom-made, they are reliable gas as to how your bullet will be performing once it reaches a certain range. In years past, they were asinine and difficult to use under pressure but many of the designs being used today are very easy to pick up on an offer an easy way to range out.
The BDC reticle rarely adds any weight, bulk or cost two Riflescope and for .308 Win the designs have all but perfected improvement in the field and on the battlefield.
Unless you will be shooting with large custom target style turrets, opt for a BDC reticle that is easy to use and clean in appearance. When you first start shooting you may not appreciate the utility of it, but over time once you start shooting further distances with holdovers, you’ll love it.
#4. One Piece and Quick Detach Mounts
Depending on the type of rifle that you have, be a Remington 700 or DPMS LR you’re going to need a mount and ring combination that works for your rifle. In the old days, this implement a Weaver style mount made for your rifles action, and a set of rings.
With the advent of everything tactical we have access to excellent one piece and quick detach mounts on the market. If you are shooting a long-range AR style rifle, consider a quick detach mount that you can easily transition to backup iron sights. For anyone shooting a precision rifle, a one-piece mount is highly recommended.
This is where the manufacturer Mills the rings and base out of one solid piece of material. This leads to tighter tolerances and less moving parts in your set up. It allows you to bed the mount to your rifle action and get the most amount of performance from your set up. They’re not much more expensive than high-quality legacy designs but are well worth the money.
#5. Fast Focus Eye Piece
Get a rifle scope with a fast focus eyepiece and generous eye box. With this refers to is the position of your eye in relation to the objective whole of the scope. If you ever look through scope and seen a black donut ring rather than a clear sight picture, you know exactly what this is. Having a fast focus eyepiece with generous eye box means that you won’t have to have your eye perfectly aligned to get rid of all parallax.
Scopes with very precise eye boxes are difficult to shoot through because you have to be extra sure each and every time you shoot that you are positioned directly behind the scope, perfectly. Small differences left and right, or up and down in relation to your eye in the scope can lead to being off target by several inches at long-range. Avoid this by using a scope with an easy to use eyepiece and I box. In all but the most critical long-range rifle set ups, you won’t notice any degradation in performance.
#6. Generous Eye Relief
If you’re not going to be using your rifle solely for bench rest shooting, get a scope generous eye relief. This is especially important if you are going to be using your scope on a scout rifle set up like you would for M1A. Having generous eye relief means that you can have your head positioned at varying links on the stock and still get the same amount of performance from your scope.
This exceptionally important if you’re going to be using your rifle for hunting, or as a lightning fast carbine. Having critical eye relief mean that you have to set up each and every shot the exact same with your cheek weld. This can get very cumbersome and slow down your shooting if you are not always going to be shooting from a very stable rest.
Scopes with critical and close eye relief are more likely to lead to scope bite and injuries due to the scope hitting you during recoil. Offer scope with generous and noncritical eye relief for anything other than a sniper style rifle set up.
#7. Warranty & Customer Service
Nothing in terms of outdoor equipment gets quite as expensive, as fast as optics. Small differences in quality and features come out to several hundred dollars once your scope is installed on your rifle. If you’re going to invest that amount of money into your equipment, make sure you’re going to protect it.
Most every major manufacturer on the market offers some sort of warranty to backup their product. Make sure the company that you are going with is well-regarded terms of customer service and honoring these warranties. The last thing you want to do is buy from a cheap fly-by-night import company that is going to leave you hanging when your scope breaks.
The American firearms industry is known throughout the world as one of the best in terms of customer service and support, take advantage of domestic manufacturers whenever possible.
When it comes to choosing a rifle scope for your .308, there are a multitude of different decisions to be made. Before you go shopping, carefully consider the type of rifle that you have in the job that you wanted to do.
With the amount of products on the market today, it’s difficult to understand the differences between each and every one of them. Each scope is going to allow you to do different things with your rifle, be it hunt in the thick brush or shoot out beyond 1000 yards.
In the end, riflescopes are very personal decision and are as much an art as they are a science. Knowing how riflescope is going perform in the field while sitting in the showroom can be difficult if you are unexperienced. Your preferences will change over time and that’s okay.
