.308-Diameter Bullets from 100 to 180 Grains: What Each Class Is Actually For
A .308-diameter bullet’s grain weight narrows the choices but does not define the job. This maintained guide maps the 100- to 180-grain classes, separates construction from weight, and preserves dated availability and replacement evidence.
This maintained guide gives shooters a durable way to compare .308-diameter bullets without pretending that weight alone defines the job. Availability, discontinued designs, replacement questions, reader evidence and controlled testing will be added as the record develops.
It does not publish load recipes. Every cartridge and bullet combination must be checked against reliable data for the exact components and firearm in use.
Start with the assignment, not the grain number
Five questions control the choice:
- Which cartridge and firearm must the bullet fit and function in?
- What target or shooting assignment must it handle?
- What nose, base, jacket and core construction serves that assignment?
- What velocity range will the bullet actually encounter?
- What evidence supports the claimed result for that exact design?
The grain weight narrows the field. It does not answer those questions.
The .308-diameter weight-class map
| Weight class | Common context | What must be distinguished | Current finding |
|---|---|---|---|
| 100 grains | Light conventional and specialty copper designs | Frangible versus controlled-expansion construction; legacy replacements | Some conventional designs appear difficult to obtain while specialty copper remains. Demand still needs to be established. |
| 110 grains | Varmint, light-recoil and high-velocity applications | Expansion rate, jacket construction and cartridge data | Many active choices. The gap is comparison, not general availability. |
| 115–120 grains | Thin specialty and compact-cartridge roles | Lead-core versus copper; factory ammunition versus component availability | A narrower shelf with intermittent availability. Dated observations matter. |
| 125 grains | Varmint, reduced-recoil, hunting and compact-cartridge choices | Construction and cartridge context | A dense, confusing field. Comparison is more useful than a shortage claim. |
| 130 grains | Conventional light .30-caliber and specialist copper designs | Conventional lead-core versus monolithic geometry and cost | Copper choices are served; conventional component shelf presence needs validation. |
| 135 grains | Light .308 applications spanning varmint, hunting, training and compact cartridges | Tip or opening, base, ogive, jacket, core and velocity intent | Unusual but obtainable. It presents a strong explanation and design-selection opportunity. |
| 140–145 grains | Sparse middle-light class | General-purpose design versus match, lever or specialist monolithic construction | A genuine catalog and explanation gap; demand is not yet proven. |
| 147–150 grains | Commodity FMJ through mainstream hunting and target use | Construction, purpose and cartridge data | Broad supply and the principal comparison baseline. |
| 155 grains | Match and Palma traditions | Ogive, bearing surface, drag design and rifle compatibility | Mature and served. Strong technical-reference opportunity; weak scarcity case. |
| 160 grains | Narrow specialty class | Exact design purpose and continuing support | Thin supply alone does not establish demand. |
| 165–169 grains | Mainstream hunting and match choices | Bonded, cup-and-core, tipped and match designs | A broad current class. Track exact discontinued designs rather than calling the whole class discontinued. |
| 170 grains | Traditional .30-30 and legacy-rifle uses | Flat or round nose, tubular-magazine safety, cartridge length and feeding | Geometry-specific replacement questions deserve a maintained ledger. |
| 175–180 grains | Heavy match and hunting uses | Exact legacy profile, jacket construction, ogive and intended velocity | A broad current class with real loyalty to particular discontinued designs. |
How Gold Country uses its design language
Match grade
When we describe a Gold Country bullet as match grade, we mean precision built to exacting standards through our hand-swaged process. We are describing manufacturing consistency, not claiming that every design is intended only for target competition.
Nose families
Our .308-diameter capability can include lead-tip, flat-nose and open-tip designs. Viper, Rhino and Scorpion are open-tip families. The family name never replaces the exact SKU’s weight, nose, base and verified specifications.
Base geometry
Our .308 bullets can be made with a flat bottom or a rebated boat tail. Every selling SKU must identify the configuration actually offered. “Can be made” is a capability statement—not permission to leave the current product unspecified.
Razorback
Razorback describes a jacket serrated at the tip. It can be applied across compatible families; it is not a separate statement of grain weight, base geometry or terminal result.
Scorpion
The maintained Scorpion design intent is controlled expansion, mass retention and deep penetration rather than rapid or explosive shallow disruption. Each SKU still requires its own verified geometry and evidence. Our 135-grain Scorpion is the .308-inch, open-tip, flat-base, 6S-ogive version formerly called Coyote.
Why equal-weight bullets are not automatic substitutes
Equal diameter and weight can hide meaningful differences in overall length, bearing surface, jacket thickness, opening or tip, ogive, base and intended velocity. Those differences can affect seating depth, usable case space, pressure, feeding and terminal behavior. A shooter replacing a discontinued bullet should seek the closest documented design—not merely the nearest grain number—and return to suitable published data.
How this guide records availability
We will not reduce availability to “available” or “discontinued.” Every maintained entry can carry one or more dated states:
- Current: the manufacturer presently lists it.
- Stocked: a named seller or distributor showed positive quantity on a stated date.
- Intermittent: current or recently current, but unevenly stocked.
- Factory ammunition only observed: loaded ammunition was found while a corresponding loose bullet was not confirmed.
- Discontinued or suspended: supported by manufacturer documentation or a clearly dated record.
- Replacement sought: shooters are asking for an exact or functional replacement. This is a demand signal, not proof of market size.
- GCA producible: we have verified tooling, materials and specifications to make the design.
- GCA listed: a canonical product record exists with an identified selling configuration.
First maintained entries
135-grain class
- Sierra #2124 HP Varminter: current manufacturer documentation and multiple cartridge data sets; Chattanooga showed stocked 100- and 500-count configurations on October 4, 2026.
- Hornady #3027 FTX: current manufacturer product page; Chattanooga showed positive stock on October 4, 2026.
- GCA 135-grain Scorpion: current selling record; .308 inch, open tip, flat base, 6S ogive and 100-count package. One recent order was for 500 bullets. We have found it useful in .300 HAM’R, .300 AAC Blackout, .308 Winchester, .30-06 Springfield and other .308-diameter rifle cartridges. In larger .30-caliber rifles, it provides a lighter-recoiling choice for enjoyable shooting, training and varmint work. Every cartridge still requires suitable data and verification for the actual rifle and loading arrangement.

165-grain bonded class
The reviewed evidence does not support saying this class has been discontinued. Current manufacturer examples remain. The useful record is design-specific: which exact product is current, intermittent or gone, what construction the shooter is trying to preserve and which candidate replacement most closely matches it.
175–180-grain match class
The weight class remains broadly served. The real problem is replacing an exact legacy profile or construction in a rifle or load that already proved itself. That belongs in the replacement ledger, not in a blanket scarcity claim.
What comes next
The next investigation covers the sparse 140- to 145-grain class. We will determine whether the thin catalog represents unmet shooter demand, a role already served by neighboring weights or a class manufacturers left because buyers did not sustain it. No product or shortage claim will precede that evidence.
Planned connected articles will also compare 125, 135 and 150 grains; 147 and 150 grains; 155, 168 and 175/178 grains; and 165 versus 168 grains. Each article will answer a narrower question and return here to the maintained record.
Help improve the record
If you are trying to replace a discontinued .308-diameter bullet, tell us the exact product, cartridge, rifle and result you are trying to preserve. Manufacturer numbers, dated packaging, chronograph records, group records, recovered bullets and original notes are more useful than a repeated claim without its source.
