The Best Powder for .308 Reloading: How to Choose a Load
How to choose a .308 powder
Choosing the right powder for .308 Winchester depends on several factors:
- Bullet weight: Lighter bullets (110–150 gr) generally perform best with faster-burning powders, while heavier bullets (168–200+ gr) usually like medium to slower-burning powders.
- Desired velocity: Do you want maximum velocity, or are you prioritizing accuracy and lower recoil?
- Rifle type: Bolt-action rifles like the Savage 110 can usually handle a wider range of powders than gas-operated semi-autos.
- Application: Target shooting, hunting, or suppressed subsonic loads all have different ideal powder characteristics.
- Temperature stability: Some powders (like Varget) are known for excellent temperature stability, which is valuable for hunters who shoot in varying conditions.
Popular Hodgdon-family powders for .308 include Varget, H4895, BL-C(2), H335, Winchester 748, and Benchmark. Each has its strengths depending on your goals.
A safe way to work up a load
Safety should always come first when developing .308 loads. Here’s a responsible approach:
- Start with published load data from a reputable manual for your specific bullet and powder combination.
- Begin at 10% below the listed maximum charge.
- Load 5–10 rounds at that starting charge and test for function and accuracy.
- Increase the powder charge in small increments (usually 0.3 to 0.5 grains for .308).
- Watch carefully for pressure signs after each increase.
- Stop immediately if you see any pressure indicators and back off.
Never jump straight to maximum loads. Work up gradually and record everything — date, powder charge, bullet, overall length, velocity, and any observations.
The giveaway’s 10 pounds is winner’s choice from Hodgdon, IMR, Winchester, Ramshot, or Accurate powders, subject to availability — so the winner can match the charge to their exact bullet and barrel.

Part of a complete reloading bench
The powder is one leg of the Day 71 reloading bench. The RCBS Rock Chucker Supreme Elite press throws and seats; the Sierra bullets give the projectile; and together they feed the suppressed Savage 110 Carbon Hunter .308 that anchors the package. Run the BANISH MeatEater on the muzzle and the same bench can build quiet subsonic loads, too.

Burn rate, explained
Powder burn rate refers to how quickly a propellant burns and generates gas pressure. Powders are ranked on a relative scale from fast-burning to slow-burning.
- Fast-burning powders (such as H335 or Winchester 748) ignite and burn quickly. They work well with lighter bullets and can produce good velocity in shorter barrels.
- Medium-burning powders (like Varget and H4895) offer an excellent balance of velocity, pressure, and accuracy. These are among the most popular choices for .308 Winchester.
- Slow-burning powders generate pressure more gradually and are typically used with heavier bullets or when higher velocities are desired.
Choosing a powder with the correct burn rate for your bullet weight helps keep pressures safe while optimizing performance. Using a powder that burns too fast with a heavy bullet can create excessive pressure, while a powder that burns too slowly with a light bullet may not reach full velocity or may leave unburned powder.
Reading pressure signs and storing powder safely
Common pressure signs to watch for:
- Difficult extraction or sticky cases
- Flattened or cratered primers
- Ejector marks on the case head
- Excessive recoil or loud report compared to previous loads
- Case head expansion or primer pocket loosening
If you see any of these signs, stop and reduce your powder charge immediately.
Powder storage safety:
- Store powder in a cool, dry place away from direct sunlight and heat sources.
- Keep it in its original containers when possible.
- Never store large quantities in living areas.
- Keep powder away from primers and other flammables.
- Follow all local regulations regarding smokeless powder storage.
Hodgdon powders are known for good stability, but proper storage helps maintain consistent performance and safety over time.

Frequently asked questions
What is the best powder for reloading .308?
A medium-burn-rate rifle powder matched to your bullet weight. The .308 Winchester has many proven options across the Hodgdon, IMR, and Winchester lines; Hodgdon Varget is a long-standing benchmark for accuracy and temperature stability. Always confirm against published load data.
How do I start working up a .308 load?
Begin at the published starting charge and increase in small, even increments toward the maximum, shooting over a chronograph and watching for pressure signs, until you find the most accurate and consistent node your rifle likes.
How much powder is in the giveaway?
Ten pounds, winner’s choice from Hodgdon, IMR, Winchester, Ramshot, or Accurate, subject to availability.
Is reloading worth it for a .308?
For shooters chasing precision or shooting in volume, yes. Handloading lets you tune the charge and bullet to your specific rifle — something factory ammunition can’t do — and gives you supply control on top of it.
Why does powder choice matter so much?
Because the charge controls velocity, and consistent velocity controls group size. The right powder, metered consistently, is what turns a good barrel into an accurate one.
