.308 Bullet Weights Explained: 147, 150, 165, 168, 175 & 180 Grain
When shopping for .308 Winchester ammunition, bullet weight is one of the first specifications you’ll notice. Common options include 147, 150, 165, 168, 175, and 180 grain, and each represents a different projectile weight.
The grain number alone does not tell you which .308 load is best. Bullet construction, projectile design, manufacturer, intended application, and the complete ammunition specification all matter.
Understanding the differences between common .308 bullet weights makes it easier to compare hunting, range, and match ammunition without getting caught up in the idea that one grain weight works for everything.
What Does Grain Mean in .308 Ammunition?
A grain is a unit of weight used throughout the ammunition industry.
When a box says 150 grain, 165 grain, or 180 grain, the number refers to the weight of the projectile.
It does not describe:
- The caliber
- The cartridge case
- The overall ammunition weight
- The bullet’s construction
- The ammunition’s pressure
- The intended application
For example, two different 165-grain .308 loads can use completely different projectile designs.
That’s why bullet weight should always be considered alongside the rest of the product specifications.
Common .308 Bullet Weights
The most frequently encountered .308 bullet weights include:
| Bullet Weight | Common Applications |
|---|---|
| 147 grain | FMJ and range ammunition |
| 150 grain | General-purpose and hunting ammunition |
| 165 grain | Hunting and general-purpose loads |
| 168 grain | Match and precision-oriented ammunition |
| 175 grain | Match and other specialized loads |
| 180 grain | Hunting and heavier-bullet loads |
These are broad categories, not strict rules. Manufacturers offer different bullet constructions and product lines within each weight.
.308 147 Grain Bullets
147 grain .308 ammunition is commonly found among FMJ and range-oriented loads.
This weight is particularly familiar to buyers shopping for practice ammunition, although the exact availability varies by manufacturer.
When comparing 147-grain loads, look at the complete product description. FMJ ammunition designed for range use is a different product category from a hunting projectile even when both are chambered in .308 Winchester.
.308 150 Grain Bullets
150 grain .308 ammunition is one of the familiar middle-weight options for the cartridge.
You’ll find 150-grain projectiles across several ammunition categories, including hunting and general-purpose loads.
The popularity of this weight means there can be substantial differences between products. A 150-grain soft point, for example, has a different purpose from a 150-grain FMJ.
If you’re comparing products, focus on the projectile construction and intended application rather than treating all 150-grain ammunition as equivalent.
.308 165 Grain Bullets
165 grain .308 ammunition sits between the common 150-grain and heavier 180-grain options.
It is widely represented in hunting ammunition and other commercial loads.
For buyers, 165 grains can be a useful reference point when comparing ammunition because it illustrates why bullet weight is only one part of the equation.
Two 165-grain loads may have different:
- Projectile construction
- Bullet shape
- Jacket design
- Intended application
- Manufacturer specifications
The grain weight stays the same, but the ammunition itself can be substantially different.
.308 168 Grain Bullets
168 grain .308 ammunition is especially familiar in match and precision-oriented ammunition.
The 168-grain weight has a long history in .308 match ammunition, and many manufacturers continue to offer 168-grain match-style loads.
However, “168 grain” does not automatically mean “match.” Manufacturers can offer different projectile types at the same weight.
Always check the product description to determine whether you’re looking at FMJ, match, hunting, or another bullet design.
.308 175 Grain Bullets
175 grain .308 ammunition is another established heavier-bullet option.
It is commonly associated with match and precision-oriented ammunition, although product availability and construction vary between manufacturers.
As with 168-grain loads, the number on the box is only the starting point. Projectile design and the manufacturer’s intended application provide additional context.
.308 180 Grain Bullets
180 grain .308 ammunition represents one of the heavier commonly encountered bullet weights in commercial .308 loads.
It is frequently associated with hunting ammunition, although manufacturers produce different 180-grain projectile designs for different purposes.
A 180-grain hunting bullet and a 180-grain projectile designed for another application should not be treated as identical simply because they share the same weight.
147 vs. 150 Grain .308
The difference between 147 and 150 grain .308 is only three grains, so the numbers alone don’t tell you much about the practical difference between two specific products.
The bigger question is what projectile each load uses.
For example, a 147-grain FMJ and a 150-grain soft point have different intended applications despite being close in weight.
When shopping, compare the complete ammunition specifications instead of focusing on the three-grain difference.
150 vs. 165 Grain .308
The 150- and 165-grain options are both widely represented in commercial .308 ammunition.
The 150-grain category is common in general-purpose and hunting loads, while 165-grain ammunition is also widely used for hunting.
Rather than asking which weight is universally better, compare:
- Projectile construction
- Intended application
- Manufacturer
- Published specifications
- Local hunting requirements
The complete load matters more than a simple three-number comparison.
165 vs. 168 Grain .308
The difference between 165 and 168 grains is also small.
Both weights appear in commercial ammunition, but 168-grain loads are particularly common in match-oriented product lines.
Again, bullet weight does not determine the entire ammunition design. A 165-grain hunting bullet and a 168-grain match projectile are intended for different purposes.
168 vs. 175 Grain .308
Both 168- and 175-grain ammunition are commonly encountered in match and precision-oriented product categories.
The difference in weight is only part of the comparison. Projectile shape and construction can be equally important when evaluating different products.
If you’re comparing ammunition for a specific application, read the manufacturer’s complete product specifications rather than choosing solely by grain weight.
175 vs. 180 Grain .308
The 175- and 180-grain categories represent heavier .308 projectiles.
175-grain ammunition is frequently associated with match-oriented loads, while 180-grain options are commonly found in hunting ammunition.
That distinction is a general market pattern, not a rule. Always check the exact projectile and product description.
Does Heavier .308 Ammo Mean More Recoil?
Bullet weight is one factor that can influence recoil, but it isn’t the only factor.
The complete ammunition load can also differ in powder charge, velocity, firearm weight, and other characteristics.
That means you shouldn’t assume that two cartridges with different bullet weights will produce a predictable difference simply from the grain numbers printed on their boxes.
For buyers, the more useful approach is to compare complete manufacturer specifications rather than trying to judge recoil from bullet weight alone.
Does Bullet Weight Determine Velocity?
No.
Bullet weight is only one component of an ammunition load.
The manufacturer’s load design, powder charge, barrel characteristics, projectile shape, and other factors all contribute to the resulting velocity.
This is why two 150-grain .308 loads can have different published specifications.
When comparing ammunition, use the manufacturer’s data for the exact product rather than relying on generalized assumptions about a particular grain weight.
.308 Bullet Weight vs. Bullet Construction
This is one of the most important distinctions to understand.
Bullet weight tells you how heavy the projectile is.
Bullet construction tells you how the projectile is designed.
A .308 cartridge could use:
- FMJ
- Soft point
- Hollow point
- Match-style projectile
- Copper or other lead-free projectile
- Other specialized designs
You can therefore have multiple 165-grain .308 loads with very different intended applications.
For ammunition buyers, construction and intended use should be considered alongside grain weight.
Which .308 Bullet Weight Is Best for Hunting?
There isn’t one universally best .308 bullet weight for every hunting situation.
Hunters should consider the specific ammunition’s projectile construction, the game being hunted, local regulations, and the manufacturer’s intended application.
A 150-, 165-, or 180-grain hunting load may all be available for .308 Winchester, but the projectile design can be just as important as the weight.
For hunting ammunition, focus on the complete load rather than selecting a grain number in isolation.
Which .308 Bullet Weight Is Best for Range Use?
For general range use, FMJ ammunition is widely available in common .308 bullet weights.
147-grain FMJ loads are particularly common in practice-oriented ammunition, while other weights are also available depending on the manufacturer.
For range buyers, cost per round, availability, ammunition specifications, and range rules are often more useful comparison points than bullet weight alone.
Which .308 Bullet Weight Is Best for Match Ammunition?
168- and 175-grain projectiles are both strongly represented in match and precision-oriented .308 ammunition.
That doesn’t mean every 168- or 175-grain product is a match load.
Look for the manufacturer’s specific designation and product description. “Match” refers to the ammunition’s intended design and specifications, not simply its bullet weight.
.308 Bullet Weight Chart
Here’s a simple reference for the common weights discussed in this guide:
| Weight | Commonly Seen In | What to Check |
|---|---|---|
| 147 grain | FMJ, range | Projectile type and manufacturer |
| 150 grain | Hunting, general-purpose | Construction and intended use |
| 165 grain | Hunting, general-purpose | Bullet design and specifications |
| 168 grain | Match, precision | Match designation and projectile design |
| 175 grain | Match, precision | Complete product specifications |
| 180 grain | Hunting, heavier loads | Hunting designation and construction |
This chart describes common market categories rather than fixed rules.
How to Choose Between .308 Bullet Weights
Instead of starting with the grain number, start with the application.
For Range Ammunition
Look for a product designed for range or target use, then compare price, availability, round count, and projectile type.
For Hunting
Start with ammunition specifically designed for hunting and verify that it complies with the regulations where you hunt.
Then compare projectile construction, bullet weight, manufacturer specifications, and intended game.
For Match or Precision-Oriented Ammunition
Look for ammunition specifically designated for match or precision applications. Compare the complete projectile and load specifications rather than selecting only by weight.
For Lead-Free Requirements
If you need non-lead ammunition, look for a product specifically identified as lead-free or using a copper or other appropriate projectile construction.
Common Mistakes When Comparing .308 Bullet Weights
Assuming Heavier Is Always Better
A heavier bullet isn’t automatically better for every application.
Treating Grain Weight as Bullet Design
A 165-grain FMJ and a 165-grain hunting bullet are not the same type of ammunition.
Choosing Based Only on the Number
The manufacturer’s complete product specification is more informative than the grain number alone.
Assuming All 150-Grain Loads Are Equivalent
Different manufacturers can use substantially different projectile designs at the same weight.
Ignoring Intended Use
Range, hunting, match, and lead-free ammunition are different product categories. Start with the application before comparing bullet weights.
Frequently Asked Questions
What are the most common .308 bullet weights?
147, 150, 165, 168, 175, and 180 grains are all commonly encountered in .308 Winchester ammunition.
Is 150 or 165 grain better for .308?
Neither is universally better. Both are available in different ammunition types, and the appropriate choice depends on the complete load and intended application.
Is 168 grain .308 good for match ammunition?
168-grain projectiles are widely represented in match-oriented .308 ammunition. However, always verify that the specific product is actually designated as match ammunition.
Is 180 grain .308 good for hunting?
180-grain .308 ammunition is widely available in hunting-oriented loads. The projectile construction and manufacturer’s intended use should be checked before selecting a specific product.
Is 147 grain .308 good for range use?
147-grain FMJ ammunition is commonly marketed for range and practice applications. Check the exact product specifications and range requirements.
Does a heavier .308 bullet have more recoil?
Bullet weight can affect recoil, but recoil also depends on other characteristics of the complete ammunition load and firearm. Grain weight alone isn’t enough to predict the difference between two specific products.
Does bullet weight affect .308 ammunition performance?
Yes, bullet weight is one factor in ammunition performance, but projectile construction, shape, load design, and firearm characteristics also matter.
Final Thoughts
The wide selection of .308 bullet weights is one reason the cartridge remains so versatile.
147-grain loads are commonly found among range ammunition, 150- and 165-grain options are widely represented in hunting and general-purpose products, 168- and 175-grain bullets are common in match-oriented ammunition, and 180-grain projectiles are frequently found in hunting loads.
But grain weight is only one specification.
When comparing .308 ammunition, look at the entire product: bullet weight, projectile construction, intended application, manufacturer, and published specifications. That gives you a much clearer picture than choosing ammunition based on the grain number alone.
