.30 (.308) Bullets for Reloading

.30 (.308) bullets for reloading

Bullets in .30 calibre normally have a diameter of .308 inch. This bullet diameter is used in a wide range of rifle cartridges, including the .308 Winchester, .30-06 Springfield, .300 Winchester Magnum, .300 AAC Blackout and modern cartridges such as the .300 PRC.

The .30 calibre is one of the most widely used bullet diameters for rifle cartridges. A broad range of bullet weights, profiles and constructions is available, allowing reloaders to select a bullet that matches the cartridge, barrel twist rate, available cartridge length and intended application.

Which cartridges use .308 bullets?

The designation .30 (.308) refers to the bullet diameter rather than a single cartridge. The same diameter is used in cartridges with very different case designs, case capacities and maximum cartridge lengths.

Common sporting and precision cartridges

• .308 Winchester – a widely used rifle cartridge for a broad range of bullet weights and shooting disciplines.
• .30-06 Springfield – a classic cartridge with a larger case capacity than the .308 Winchester.
• .300 Winchester Short Magnum – commonly known as the .300 WSM and built around a short, wide magnum case.
• .300 PRC – a modern cartridge designed to accommodate long and relatively heavy .308 bullets.
• .300 Norma Magnum – a modern magnum rifle cartridge for long and heavy .30-calibre bullets.

Magnum rifle cartridges

• .300 Winchester Magnum – a widely used magnum rifle cartridge for a broad range of .308 bullet weights.
• .300 Weatherby Magnum – a magnum rifle cartridge with a large case capacity.
• .300 Remington Ultra Magnum – also known as the .300 RUM and designed for high-capacity loads.
• .300 Holland & Holland Magnum – a classic magnum rifle cartridge with a long case.
• .30 Nosler – a modern cartridge for heavy .308 bullets.
• .300 Dakota – a magnum rifle cartridge with a comparatively large case capacity.

Compact and efficient cartridges

• .300 AAC Blackout – a compact cartridge that uses both lightweight and heavy .308 bullets.
• .300 HAM’R – a compact .30-calibre cartridge developed around a relatively short case.
• .30 BR – a compact cartridge used in certain precision shooting disciplines.
• .30 TCU – based on a modified .223 Remington case and designed for .308 bullets.

Classic and European cartridges

• .30-30 Winchester – a classic rimmed cartridge commonly used with bullets suitable for tubular magazines.
• .300 Savage – a classic American rifle cartridge with a compact case.
• .303 Savage – despite its name, this cartridge generally uses .308-inch bullets.
• 7.5×55 Swiss – a Swiss military and sporting cartridge using .308-inch bullets.
• 7.62×51 NATO – closely related to the .308 Winchester, but with its own specifications and load data.
• 7.62×39 – normally uses a larger bullet diameter than .308 inch and therefore does not usually belong in this category.

Not every .308 bullet is automatically suitable for all the cartridges listed above. Bullet weight, length, profile and construction should match the exact cartridge, barrel twist and available space in the rifle.

Types of .30-calibre bullets

.30-calibre bullets are available in many different constructions. The most suitable design depends on the cartridge, shooting discipline, distance and the requirements of the completed ammunition.

• Match bullets – intended for shooters who value consistent shape and weight distribution.
• Hollow Point Boat Tail – combines a hollow point with a tapered rear section.
• Polymer- or aluminium-tipped bullets – fitted with a separate tip as part of a streamlined bullet profile.
• Soft Point – constructed with a partially exposed lead tip.
• Flat Point – designed with a flat nose and used in certain lever-action cartridges.
• Round Nose – a rounded bullet profile commonly found in classic cartridge combinations.
• Bonded bullets – manufactured with the core bonded to the jacket.
• Monolithic bullets – made from a single material such as copper or a copper alloy.
• Boat Tail – designed with a tapered rear section.
• Flat Base – constructed with a flat base and often a shorter overall bullet length.

Choosing the correct bullet weight

Bullet weight is measured in grain. Within the .30 calibre, reloaders can choose from very light bullets, medium-weight designs and long, heavy bullets. The correct weight class depends on the cartridge, barrel twist rate and available load data.

Lighter bullets may be used in loads where a higher muzzle velocity is preferred. Medium-weight bullets are suitable for many different cartridges. Heavy and long bullets often have a more favourable ballistic profile and can retain velocity more effectively over longer distances.

The .300 AAC Blackout, for example, is loaded with both lightweight and very heavy bullets. A heavy bullet may be significantly longer than a light design, making seating depth and available case volume especially important.

Bullets of the same weight can still differ considerably in length and construction. A monolithic bullet is often longer than a traditional lead-core bullet of identical weight. Always consider bullet length and construction as well as weight.

Barrel twist and stabilisation

The barrel twist rate indicates the distance over which the bullet completes one full rotation. Long and heavy .308 bullets generally require a faster twist rate than short and light designs.

With long match bullets and heavy bullets for .300 AAC Blackout in particular, it is important to confirm that the barrel provides sufficient stabilisation. Stability depends not only on bullet weight, but also on length, shape, material and velocity.

Always consult the information provided by the rifle and bullet manufacturers. Use current load data developed specifically for the exact cartridge and bullet combination.

Differences between .30-calibre cartridges

Although cartridges such as the .308 Winchester, .30-06 Springfield, .300 Winchester Magnum, .300 AAC Blackout and .300 PRC use the same bullet diameter, their cases differ considerably in shape, capacity and maximum cartridge length.

Load data is therefore never interchangeable between different .30-calibre cartridges. Even when the same bullet is used, powder type, powder charge, primer selection and seating depth must match the exact cartridge.

The .300 AAC Blackout uses a compact case, while the .300 Winchester Magnum and .300 PRC have much greater case capacities. The .308 Winchester and .30-06 Springfield use the same bullet diameter but differ clearly in case dimensions and load data.

Cartridge length and seating depth

Long .308 bullets can affect cartridge overall length and the available internal case volume. The usable length is influenced by the magazine, chamber and throat dimensions.

Changing seating depth also changes the available case volume. This may affect the characteristics of the load. Adjust seating depth only on the basis of reliable load data and verified measurements.

Special considerations for tubular magazines

For cartridges used in rifles with tubular magazines, such as certain .30-30 Winchester rifles, bullet nose shape must be taken into account. Pointed bullets may rest against the primer of the cartridge in front of them inside the magazine.

For these applications, use only bullets that reliable load data and the manufacturer identify as suitable for the relevant magazine system.

What should you consider?

• Confirm that the bullet has the correct diameter of .308 inch.
• Use only current load data for the exact cartridge and bullet.
• Match bullet weight and length to the barrel twist rate.
• Check maximum cartridge overall length and available magazine space.
• Consider bullet profile, construction and overall length.
• Never interchange load data between different .30-calibre cartridges.
• Do not substitute another bullet without verification, even if the weight is identical.
• For tubular magazines, confirm that the selected bullet profile is suitable.
• Always begin with the recommended starting load from a reliable source.
• Inspect every completed cartridge carefully before use.
