6 mm (.243) Bullets for Reloading

6 mm (.243) bullets for reloading rifle cartridges

Bullets in 6 mm calibre normally have a diameter of .243 inch. This bullet diameter is used in a wide range of rifle cartridges, including .243 Winchester, 6 mm Creedmoor, 6 mm Remington, 6 mm BR Norma, 6 mm Dasher and 6 mm ARC.

The 6 mm calibre is widely used in target shooting because it combines a relatively slender bullet profile with favourable ballistic performance and generally moderate recoil. The correct bullet depends on the cartridge, barrel twist rate, maximum cartridge length and the discipline for which the ammunition is being loaded.

Which cartridges use .243 bullets?

The designation 6 mm (.243) refers to the diameter of the bullet rather than one specific cartridge. The same bullet diameter can therefore be used in several calibres. Always use load data written for the exact cartridge and bullet selected.

• .243 Winchester – a widely used cartridge for target shooting and hunting, based on a necked-down .308 Winchester case.
• 6 mm Creedmoor – developed for longer 6 mm bullets with favourable ballistic coefficients.
• 6 mm Remington – originally introduced as the .244 Remington and later renamed 6 mm Remington.
• 6 mm BR Norma – a compact cartridge commonly used in precision and benchrest shooting.
• 6 mm Dasher – a development of the 6 mm BR that is widely used in benchrest and long-range disciplines.
• 6 mm PPC – a classic benchrest cartridge built around a short and efficient case.
• 6 mm ARC – a modern cartridge developed to use longer 6 mm bullets in a compact platform.
• 6 mm XC – a competition cartridge suited to a range of medium and heavy 6 mm bullets.
• 6×45 mm – based on a .223 Remington case with the neck expanded to accept a .243 bullet.
• .243 Winchester Super Short Magnum – commonly abbreviated to .243 WSSM and built around a short, wide case.
• 6 mm GT – a modern competition cartridge designed for longer 6 mm match bullets.

Not every .243 bullet is automatically suitable for all of these cartridges. Bullet weight, length, construction and required cartridge overall length all influence whether a bullet can be used in a particular combination.

What will you find in this category?

This category contains 6 mm bullets mainly intended for precision shooting and use at longer distances. The current range includes Hornady BTHP Match bullets in 105 grain and Hornady A-Tip Match bullets in 110 grain.

• BTHP Match – a match bullet with a hollow-point design, boat tail and streamlined profile.
• A-Tip Match – a long match bullet with an aluminium tip and a shape developed for favourable ballistic performance.
• Heavy 6 mm bullets – intended for cartridges and barrels suitable for long bullets of around 100 grain or more.
• Boat-tail profiles – designed with a tapered rear section that may improve airflow around the bullet.

Hornady 6 mm match bullets

Hornady offers several 6 mm match bullets for shooters who pay close attention to bullet shape, weight distribution and ballistic performance.

The Hornady BTHP Match 105 grain combines a hollow-point construction with a boat tail. This weight class is commonly used in cartridges such as 6 mm Creedmoor, 6 mm BR Norma, 6 mm Dasher and similar 6 mm competition cartridges.

The Hornady A-Tip Match 110 grain is a longer and heavier bullet fitted with an aluminium tip. Because of its length and weight, this design places greater demands on barrel twist and available cartridge length than many lighter 6 mm bullets.

Bullet weight and application

Bullet weight is expressed in grain. Within the 6 mm calibre range, bullet weights vary from light designs for higher velocities to long match bullets weighing 100 grain or more.

Lighter 6 mm bullets are often used when high initial velocity is preferred. Heavier designs generally retain velocity better and often have a higher ballistic coefficient. This makes them particularly suitable for disciplines where shooting takes place at longer distances.

A heavier bullet is not automatically suitable for every 6 mm cartridge or rifle. Barrel twist, chamber length, magazine space and available load data remain decisive.

Barrel twist and stabilisation

The barrel twist rate indicates the distance over which the bullet completes one full rotation. Long and heavy 6 mm bullets generally require a faster twist rate than short and light designs.

For bullets weighing 105 or 110 grain, it is important to check whether the barrel is capable of providing sufficient stabilisation. Bullet length, shape and material construction are just as important as weight.

Always consult the information provided by the rifle and bullet manufacturers. The velocity reached by the selected load should also be taken into account.

Differences between .243 Winchester and modern 6 mm cartridges

Although .243 Winchester, 6 mm Creedmoor, 6 mm BR Norma and 6 mm Dasher use the same bullet diameter, their cartridge cases differ considerably in shape and capacity. Their load data is therefore not interchangeable.

The .243 Winchester is based on the .308 Winchester case and offers relatively large case capacity. The 6 mm BR Norma and 6 mm Dasher use more compact and efficient cases and are mainly used in precision disciplines. The 6 mm Creedmoor was developed with space for longer aerodynamic bullets and is widely used in modern long-range shooting.

What should you consider?

• Check that the bullet has a diameter of .243 inch.
• Use only current load data for the exact cartridge and bullet selected.
• Match bullet weight and length to the barrel twist rate.
• Check the maximum cartridge overall length and available magazine space.
• Take the throat and chamber design into account.
• Never interchange load data between different 6 mm cartridges.
• Do not use data for another bullet without verification, even if the weight is identical.
• Check whether long match bullets must be seated deeper or farther forward while remaining within the permitted specifications.
