Caliber Description
The 6.5x68 caliber is a storied cartridge with a rich history that dates back to the late 1930s. Originally developed in Germany by ammunition maker RWS (Rheinisch-Westfälische Sprengstoff-Fabriken), the 6.5x68 was first introduced to the public in 1939, alongside its larger sibling, the 8x68S. The timing of its release, right before World War II, hampered its initial widespread adoption, but it quickly garnered a reputation among European hunters for its high velocity and very flat trajectory. The case design is based on the 8x68S, necked down to accept 6.5mm bullets, offering superior ballistics compared to other 6.5mm cartridges of its time. The 6.5x68 stands out for its engineering, as it was specifically designed for Mauser-style long-action rifles, making it an appealing choice for those who valued German rifle craftsmanship.
In terms of applications, the 6.5x68 excels as a long-range hunting and sporting cartridge. Its flat trajectory and high retained velocity make it especially suitable for use in wide open spaces, such as the rolling plains and mountainous regions of Europe. Originally, the cartridge was mostly favored by European hunters pursuing chamois, red deer, and roe deer, but its performance has been noticed by international shooters and reloaders as well. The cartridge’s ability to maintain supersonic speeds past 400 meters allows for precise shot placement even at extended distances. Additionally, the hard-hitting nature of 6.5x68 has made it popular among those who want to harvest game ethically with minimal risk of wounding.
When it comes to target species, the 6.5x68 is particularly effective for medium to large game. It is a popular choice for European hunters targeting red stag, chamois, mouflon, and wild boar. Because of its high velocity and flat shooting characteristics, it’s also used occasionally for long-distance shooting competitions, especially by aficionados who favor classic cartridge designs. Its ballistic efficiency, penetration, and knockdown power make it well-suited for animals weighing up to several hundred kilograms. However, it’s worth noting that local regulations sometimes restrict its use for the largest game, such as moose or brown bear, where heavier calibers are preferred or mandated.
Regarding bullet weights and other caliber characteristics, the 6.5x68 typically utilizes bullets in the 93 to 140 grain range, with 120, 127, and 140 grain projectiles being the most common choices for reloaders focused on big game. Due to its large case capacity and relatively narrow bore, the cartridge is capable of reaching muzzle velocities between 3,200 and 3,600 feet per second, depending on bullet weight and powder selection. The long neck of the case allows for secure seating of longer, high ballistic coefficient (BC) projectiles, while its robust construction ensures dependable feeding and extraction. Reloaders should note, however, that the 6.5x68 is known for relatively short barrel life compared to milder 6.5mm cartridges, due to intense throat erosion caused by high velocities and pressures. As such, careful load development and diligent cleaning are recommended to maximize performance and rifle longevity. Despite this, the 6.5x68 remains a favorite among experienced reloaders who appreciate its unmatched performance in a classic European package.

Always start lower and work up loads, check multiple sources, and watch for pressure signs.
Cost per Reloaded Round
Let’s do a sample calculation based on commonly available data:
Factory ammunition price for 6.5 x 68:
Typically, factory-loaded 6.5 x 68 ammunition is relatively expensive due to its specialty status. Prices as of 2023 are about $90 to $120 per box of 20.
Let’s use $100 for 20 rounds, which is $5.00 per round.
Reloading cost estimate (per round):
- Brass cases: $2.00 each (Lapua or Norma), but reusable, so cost per firing is less. Let’s assume 10 reloads per case: $0.20 per shot.
- Primers: $0.10 each
- Powder: Assume 55 grains per load, 7000 grains per lb, so 127 rounds per lb. Powder cost about $40 per lb; $40/127 = $0.31 per round.
- Bullets: High-quality 6.5 mm hunting bullet approximately $0.60 each.
Total reloading cost per round:
$0.20 (brass) + $0.10 (primer) + $0.31 (powder) + $0.60 (bullet) = $1.21 per round
Money saved per round:
$5.00 (factory) - $1.21 (reloading) = $3.79 saved per round
Therefore, you save approximately $3.80 per round by reloading 6.5 x 68 instead of buying factory ammunition.
